I installed a 10MW system with Solartech over 10 years ago, but it has given me an average of +14MW per year, and they still deliver above the bar service. Great people, direct, fast, nice, competent and scheduling folks are great!

SolarTech came out within 24 hours of my reaching out to them. They fixed the problem on my roof with my pool solar system. Robert also noticed a broken component and was able to replace the part quickly and inexpensively. Thanks SolarTech for the two-in-one appointment!

Frequently Asked Solar Panel Cost Calculator Questions

A solar panel cost calculator is a free online tool that estimates how much solar panels might cost for your home and how much you could save on energy bills. It uses your energy usage, location, and other inputs to give a personalized estimate of system cost, size, monthly payments, and long-term savings.

This calculator asks you a few simple questions — like your monthly electric bill, roof shading, and system preferences — and then uses industry-standard solar production data to estimate your solar system cost, potential savings, and payback timeframe.

The estimate is a personalized projection based on your inputs and real solar performance data. While it provides very useful cost and savings ranges, final pricing can vary based on roof condition, equipment choices, and permits — just like any solar quote.

 

To get an accurate cost and savings estimate, the calculator may ask for your address (for roof and solar resource data). You’ll also enter basic contact info so we can send your results and follow up with a custom solar quote if you choose.

No — the calculator is 100% free. It gives you an upfront estimate so you can make an informed decision without pressure.

Yes — one of the biggest benefits of using this tool is estimating your monthly bill savings, 25-year savings, and approximate payback period based on your location and utility rates.

After receiving your solar panel cost estimate, you can review your personalized cost & savings details, get a free full solar quote from our experts, or speak with a SolarTech advisor to design the best system for your home.
