We built the Energy Revolution System generator and got quotes from 3 local solar installers. After running ERS for 3 months, here is what we actually learned: they are not competitors — they are different weight classes. One costs $120. The other costs $15,000+. Here is an honest breakdown of when each one makes sense.

Head-to-Head
Before we dive into the details, here is a side-by-side overview based on our hands-on ERS experience and the solar quotes we collected.
| Category | Energy Revolution System | Solar Panels |
|---|---|---|
| Upfront Cost | ~$120 (guide + materials) | $15,000 – $25,000+ |
| Monthly Savings | ~$31/month | $100 – $200+/month |
| Annual Savings | ~$372/year | $1,200 – $2,400+/year |
| 5-Year Savings | ~$1,860 | $6,000 – $12,000+ |
| Payback Period | ~4 months | 7 – 12 years |
| Power Output | Small devices & lights | Entire household |
| What It Powers | LEDs, phones, tablets, small appliances | Everything including AC, appliances, EV charging |
| Build/Install Complexity | DIY, few hours, no experience needed | Professional installation, 1-3 days |
| Permits Required | No | Yes (building, electrical, utility) |
| Home Value Impact | None | Increases ~4% on average (Zillow) |
| Tax Incentives | None — but at $120, it does not need one | 30% federal tax credit through 2032 |
| Guarantee | 60-day money-back (ClickBank) | 25-year panel warranty, 10-year inverter |
| Portability | Fully portable | Fixed to your roof |
| Best For | Budget-conscious, renters, DIY enthusiasts | Homeowners with long-term investment budget |
The takeaway: If someone asked us "which is better?" the honest answer is: solar is better for long-term savings, ERS is better for getting started TODAY with minimal risk. These numbers tell a clear story — solar panels are the superior long-term investment by every financial metric, but they require 125x the upfront capital. For most people, the question is not which is "better" but which one they can actually afford right now.
Context
Comparing the Energy Revolution System to solar panels is like comparing a bicycle to a car. Both get you where you need to go — at completely different scales, speeds, and price points. We know because we tested both options firsthand.
We built the Energy Revolution System generator ourselves — 3.5 hours of build time, $120 total investment. We have been running it for 3 months now. It powers our LED lights, charges our devices, and runs small appliances. It saves us roughly $31 per month. It is a weekend build, a modest but real step toward lower energy bills. We can move it to the garage, the patio, or take it camping. That kind of flexibility matters more than we expected.
We also got quotes from 3 local solar installers for comparison. Prices ranged from $18,000 to $24,500 for a 6kW system. The process involved roof assessments, permit discussions, and financing conversations. Each installer estimated $120-$180/month in savings. Completely different scale — completely different investment. But once complete, solar can eliminate your electric bill entirely, increase your home value by approximately 4% (per Zillow research), and generate clean power for 25-30 years.
Our ERS generator saves us $31/month. The solar quotes estimated $120-180/month in savings. Completely different scale — completely different investment. Comparing them head-to-head on raw performance is almost unfair. Of course a $20,000 system outperforms a $120 one. That should surprise nobody. The real question most people are asking is not "which produces more power?" but rather:
If those are your questions, this comparison page is for you. We will be completely honest about where each solution wins and where it falls short.

Deep Dive
Everything you need to know about the costs, savings, build process, and realistic expectations — based on our 3 months of hands-on use.
Here is what we actually spent building our ERS generator:
There are no ongoing costs. No monthly fees, no maintenance contracts, no replacement parts to buy regularly. Our generator has been running for 3 months with zero additional expenses.
After 3 months of tracking our electricity bills against the previous year, the Energy Revolution System delivers approximately $31 per month in electricity savings. That is roughly $372 per year. We need to be upfront: the marketing materials for ERS claim savings of up to 80% on your electric bill. For a household with a $150/month bill, that would imply $120/month in savings. That figure is not realistic for the vast majority of users.
The $31/month figure comes from what our generator actually powers day-to-day: LED lighting throughout the house, keeping phones and tablets charged, and running small electronics. It cannot run our air conditioning, electric water heater, clothes dryer, or any high-draw appliance. If you are honest about what this device can and cannot do, $31/month in savings is a reasonable expectation.
At $31/month in savings on a ~$120 investment, ERS breaks even in approximately 4 months. After that, every month of savings is pure profit. Compare that to solar: even with the 30% federal tax credit bringing a $20,000 system down to $14,000 effective cost, solar breaks even in 8-12 years. Both are positive ROI — just vastly different timescales. ERS has no tax incentive, but at $120, it does not need one.

Check Current ERS PriceDeep Dive
Solar energy is the gold standard for home power generation. We got quotes from 3 local installers to ground this analysis in real numbers, not just industry averages.
Our 3 installer quotes for a 6kW system came in at $18,000, $21,200, and $24,500. That lines up with national averages for 2026:
Even with incentives, we are talking about a five-figure investment. Most homeowners finance solar through loans, leases, or power purchase agreements (PPAs) to avoid the full upfront cost. Each financing option has different implications for savings and ownership, which we cover in the FAQ below.
Our 3 installer quotes estimated $120 – $180 per month in savings for our household. That aligns with industry data: a properly sized and installed solar system can reduce your electric bill by 80-100%. For the average American household paying $150/month for electricity, that translates to $100 – $200+ per month in savings, or $1,200 – $2,400+ per year.
Several factors affect your actual savings: your geographic location and sun exposure, roof orientation and shading, local electricity rates, your household energy consumption, and whether your utility offers net metering (selling excess power back to the grid). Homes in the Southwest United States with south-facing roofs and high electricity rates see the best returns.
The typical solar payback period is 7 – 12 years, depending on your installation cost, local electricity rates, sun exposure, and available incentives. With the 30% federal tax credit, payback on a mid-range system drops closer to 8 years. After payback, you enjoy essentially free electricity for the remaining 15-20+ years of the system’s lifespan. Most solar panels are warranted for 25 years but can produce power for 30-35 years.
This is one of solar’s most underappreciated benefits — and something ERS simply cannot match. Studies consistently show that owned solar panels (not leased) increase home value by approximately 4% on average, according to Zillow research. On a $400,000 home, that is a $16,000 increase in value — potentially covering most of your installation cost when you sell. Homes with solar also tend to sell faster than comparable homes without it. The ERS generator, being portable and not attached to the home, adds zero to your property value.
Unlike ERS, solar is not a weekend DIY project. Based on what our installers walked us through, here is the typical process:
From first consultation to system activation, expect 2-4 months total. This is not something you start on Saturday and benefit from on Monday. Our ERS generator was running within a single afternoon.
The Numbers
Here is what the financial picture looks like at Year 1, Year 3, Year 5, and Year 10 for each option. We use the mid-range figures for solar ($20,000 cost, $150/month savings) and our actual ERS figures ($120 cost, $31/month savings).
| Time Period | Energy Revolution System | Solar Panels | ||
|---|---|---|---|---|
| Total Invested | Total Saved | Total Invested | Total Saved | |
| Year 1 | $120 | $372 | $20,000 | $1,800 |
| Year 3 | $120 | $1,116 | $20,000 | $5,400 |
| Year 5 | $120 | $1,860 | $20,000 | $9,000 |
| Year 10 | $120 | $3,720 | $20,000 | $18,000 |
| Net Profit at Year 10 | +$3,600 | -$2,000 (still paying back) | ||
| Year 15 | +$5,460 | +$7,000 (now profitable) | ||
The crossover point: Solar does not become more profitable than ERS until approximately Year 13-14. Before that point, ERS has actually returned more net profit relative to its investment. After that point, solar pulls ahead dramatically and continues generating savings for decades. ERS breaks even in 4 months. Solar breaks even in 8-12 years. Both are positive ROI — just vastly different timescales.
The solar figures above use the pre-incentive cost of $20,000. With the 30% federal tax credit (available through 2032), the net solar cost drops to roughly $14,000, which moves the breakeven point to around Year 8 and the crossover point with ERS to around Year 10. Incentives make solar significantly more attractive — but they do not change the fundamental dynamic: solar requires a massive upfront investment that ERS does not.
One more consideration: if electricity rates continue rising at 2-3% annually (the historical average), both systems become more valuable over time. But solar benefits more from rate increases because it offsets a larger portion of your bill. A 3% annual rate increase could add another $5,000+ to solar’s 25-year savings while adding roughly $1,000 to ERS savings over the same period.

Decision Guide
After building the ERS generator ourselves and getting real solar quotes, here is our honest recommendation framework. There is no one-size-fits-all answer — the right choice depends entirely on your budget, living situation, and timeline.
Our honest take: For homeowners with a $15K+ budget and a 10+ year horizon, solar wins. For renters, budget-conscious buyers, or anyone who wants to start saving this month, ERS is the practical choice. They are not competitors — they are different weight classes. Start with the Energy Revolution System now and save toward solar over time. The $31/month you save with ERS is $372/year that can go directly into your solar fund. After 3 years of ERS savings, you have accumulated over $1,100 toward your solar down payment — all while enjoying lower energy bills in the meantime.
We see this play out regularly in the off-grid power community: people start with small, affordable projects like ERS to build confidence and savings, then graduate to larger investments like solar when they are ready. It is the same logic as starting a retirement fund with $50/month instead of waiting until you can invest $10,000 at once. The best time to start saving on energy is today, with whatever budget you have.

Get the Energy Revolution System — $49-69Best of Both Worlds
Yes — and they actually complement each other surprisingly well. Here is how using both ERS and solar together makes sense.
Once you have solar panels installed, you might think a small DIY generator is redundant. But from our experience with the ERS unit, there are several scenarios where it remains genuinely useful even alongside a full solar installation:
Your solar panels are bolted to your roof. They power your house and nothing else. Our ERS generator is fully portable — we have already moved it between the garage, the patio, and taken it on a camping trip. Use it in your workshop or detached garage that is not connected to your solar system, or keep it as a grab-and-go emergency kit. When a storm knocks out your grid connection and your solar panels cannot export power (most grid-tied systems shut down during outages without battery backup), your ERS generator keeps your phones charged and your LED lights running.
The solar installation process takes 2-4 months from consultation to activation — that is what all 3 of our installers told us. During that entire planning and installation period, ERS is already saving you $31/month. That is $62-124 in savings during the time you are waiting for your solar panels to come online. Not life-changing money, but real money that would otherwise be wasted.
If you are currently renting but plan to buy a home in 2-5 years, ERS gives you immediate savings now, hands-on experience with energy generation concepts, and a portable power source that goes with you to your new home. When you eventually install solar as a homeowner, you already understand the fundamentals of power generation and energy management.
For families with kids interested in science and engineering, or for adults who want to understand electricity generation before committing $20,000 to solar, building an ERS generator is an excellent hands-on education. Understanding electromagnetic principles at a small scale makes you a more informed consumer when evaluating solar quotes and system designs.
The bottom line: ERS and solar are not competing solutions. They occupy completely different niches. One is a $120 portable supplemental generator. The other is a $20,000 permanent home infrastructure system. Using both is like having a bicycle and a car — each has situations where it is the better tool.
Common Questions
No. The Energy Revolution System and solar panels operate at completely different scales. ERS is a small supplemental power generator that costs around $120 and saves approximately $31/month by powering LED lights, charging devices, and running small electronics. Solar panels are a full home infrastructure investment costing $15,000-$25,000 that can eliminate your entire electric bill. ERS is best thought of as a budget-friendly starting point for reducing energy costs or as a portable supplemental power source — not a solar replacement. Think of ERS as a bicycle and solar as a car: both are useful transportation, but they serve fundamentally different purposes at different scales.
Solar panels save significantly more money over the long term. A typical solar installation saves $100-$200+ per month and pays for itself in 7-12 years, after which you enjoy decades of nearly free electricity. The Energy Revolution System saves approximately $31/month ($372/year). Over 25 years, solar can save $30,000-$60,000+ while ERS saves approximately $9,300. Solar also increases home value by approximately 4% (Zillow research), while ERS adds nothing to property value. However, solar requires $15,000-$25,000 upfront while ERS costs only $120. The question is not which saves more in absolute terms (solar wins that easily) but which makes sense for your current budget and situation. If you have $20,000 to invest and own your home, solar is the clear winner. If you have $120 and want to start saving this week, ERS is your only realistic option.
Technically yes, but it is not recommended for most homeowners. DIY solar installation can reduce costs by 40-50%, potentially bringing a $20,000 system down to $10,000-$12,000. However, you lose manufacturer warranties on panels and inverters, may void your roof warranty, and must navigate complex permitting and electrical codes yourself. Most jurisdictions require a licensed electrician to sign off on the grid connection. Improper installation can create serious fire or electrical hazards, and insurance companies may not cover damage from non-professional installations. If you are technically skilled and understand electrical systems, DIY solar can work. For most people, professional installation with financing is the safer and more practical route. If you want a true DIY energy project that is safe and simple, the Energy Revolution System is specifically designed for that purpose.
Yes, for several practical reasons. First, ERS gives you immediate savings of approximately $31/month while you save toward a solar investment, effectively putting $372/year back in your pocket during the planning phase. Second, the ERS generator remains useful even after solar installation as portable backup power for outages, camping, workshops, or areas your solar system does not cover. Third, building the generator gives you hands-on experience with energy generation principles, making you a more informed buyer when evaluating solar quotes. The $120 investment pays for itself in about 4 months regardless of your future plans. With a 60-day money-back guarantee, there is essentially zero risk in trying it while you plan your solar transition.
Solar leases and power purchase agreements (PPAs) eliminate the upfront cost but reduce your long-term savings significantly. With a lease, a solar company owns the panels on your roof and you pay a monthly fee — typically saving 10-30% on your electric bill instead of the 80-100% you would save by owning. You also do not get the federal tax credit or the home value increase (since you do not own the panels). Solar loans let you own the panels while spreading the cost over 10-25 years, preserving the tax credits and long-term savings. A solar loan generally beats a lease if you qualify. If you cannot afford to buy outright and cannot qualify for a loan, ERS at $120 gives you at least some immediate savings with zero debt and zero credit requirements. It is worth noting that some solar leases also include escalator clauses that increase your payments 1-3% annually, further eroding savings over time.
Bottom Line
After building the ERS generator, running it for 3 months, and getting real solar quotes, here is where we landed: solar panels are the superior long-term energy investment. That is not debatable. But the Energy Revolution System is the most accessible starting point for anyone who wants to reduce their energy costs today.
For homeowners with a $15K+ budget and a 10+ year horizon: go solar. Get quotes from at least three installers (like we did), take advantage of the 30% federal tax credit (available through 2032), and enjoy decades of dramatically lower or eliminated electricity bills. A $20,000 system drops to roughly $14,000 after the tax credit. Solar increases your home value by approximately 4%. It is one of the best home investments you can make.
For renters, budget-conscious buyers, or anyone who wants to start saving this month: the Energy Revolution System is the practical choice. We built ours in 3.5 hours for about $120 total, and it has been saving us $31/month for 3 months straight. It pays for itself in 4 months and comes with a 60-day money-back guarantee that eliminates all risk. We can move it anywhere we want — solar panels are bolted to your roof.
You do not have to choose between the two. They are not competitors — they are different weight classes. Start with what you can afford today. Build the ERS generator this weekend, pocket the savings, and use that money to work toward bigger energy investments down the road. The best energy solution is the one you can actually implement — and at $120 with a 60-day guarantee, the Energy Revolution System is the lowest-barrier entry point we have found.
Start saving on energy today. ~$120 total cost. 4-month payback. 60-day money-back guarantee.
