Disclaimer
Estimates, not quotes. Our calculators and state pages use averages from public data. Your real costs and savings depend on your utility rate plan, how and when you use power, your vehicle, your roof, local prices and many other factors. Always get written quotes before you buy.
Not advice. Nothing on this site is financial, investment, tax, legal or engineering advice. Tax credits and rebates have eligibility rules and deadlines; check with the IRS, your state, your utility or a qualified professional.
Product information.Vehicle and battery prices and specifications change often. Battery, power station and plug-in solar specifications and prices on our guides are copied from the manufacturer's own US product pages and dated; the EV Finder list is gathered by automated research. Prices move daily, so confirm details with the manufacturer or dealer before you buy.
Installer listings. The Solar Finder lists companies that say they serve your state. We have not inspected their work, and a listing is not an endorsement. Check licenses, reviews and certifications yourself.
Third-party news. Headlines on our news page belong to their publishers. We link to their articles and are not responsible for their content.
Electrical work. Chargers, solar panels and batteries must be installed by licensed professionals under local codes and permits.
Affiliate disclosure: how we make money
Spark Powered is free to use. Some links to products and services, such as portable power stations, home batteries, plug-in solar kits and solar quote marketplaces, are affiliate links. If you buy or sign up through one, the seller may pay us a commission. You pay the same price.
Commissions never change our recommendations. We choose products from their published specifications, prices and warranties, using the method described on each guide. We list products from brands that pay us nothing alongside those that do, and a brand cannot pay to be included, ranked higher or described more kindly.
Affiliate links are marked as sponsored for search engines and open in a new tab. Pages that contain them say so near the top. Our calculators and state data do not depend on any partner.
We do not publish star ratings or customer reviews, and we have not bench-tested every product we list; where we compare products, we say exactly which published figures we compared.
