Our Reviews

Here are some 5 star reviews from our customers on Google.

Nick Hennicke

If you are thinking of going solar, Astrawatt is the ONLY way to go. I am not kidding. I had 7+ quotes from various companies. Local little companies, giant nationwide companies, companies out of california, etc. This company ACTUALLY knows what they are talking about. Bryan B is what initially sold me on this company. His knowledge and clarity at the start of this process was incredible. He explained in great detail how solar works in my state with our local utility company (ameren). He explained everything from how overproduction would actually work, to sizing the system appropriately. He also explained in great detail the loan process, and various styles of loans (and what fees come with each one). Not one other company even came close to Bryan's explanation. Tim and the rest of the team were also very helpful throughout the whole process. Ryan was great during the install, and install went smooth and inspection cleared without problem. Very professional throughout the entire time. Basically summary: If you are thinking of going solar, before you commit to another company, PLEASE talk to Bryan B or one of the reps. They are incredible and so much more helpful and clear than any company. 5 stars!

Ryan and the crew were professional and efficient. They explained everything they were doing and answered all my questions. The installation was just completed today so I can't speak to the performance of the equipment but if it is anything like the installation I will be very pleased.

Today, March 31, 2022, my inspection for my solar system was completed by St. Louis County. Everything including sales, permitting, installation, and inspection was perform by extremely professional and friendly personnel. I have the highest praise for the quality of work and knowledge of team members Bryan, Megan, Jeff, Ryan, Nick, and Jamie. I am excited and eager for Ameren to install my bi-directional meter.

They did a good job, a bit chaotic at first, but they did get the job done on time. An accident happened with a wasp nest in the attic causing a hole in my ceiling. The guys said the company would send someone out to fix it (hence the four stars or I would have given five stars). I will update it when that happens. *****Update***** They had someone out within a few days and they fixed the hole perfectly. I updated the stars also.

Missouri Solar Incentives and Tax Credits

Federal Solar Tax Credit

The Investment Tax Credit (ITC), also called the federal solar tax credit, helps you reduce the cost of your solar energy system. You can deduct 30% of the cost of your solar energy system from your federal income taxes. There is no cap on the value of your tax credit and it applies to both residential and commercial systems.

The federal solar tax credit was recently increased to 30% and its timeline has been extended. If you install a solar PV system between now and 2032 you will receive a 30% tax credit. If you’ve already installed your solar system in 2022, your tax credit has been increased from 26% to 30% and you can take advantage of the increased tax savings.

Net Metering in Missouri

Net Metering is when your utility company monitors how much energy your home’s solar system produces and how much energy you consume. If your home’s solar system generates a surplus of energy, you will receive a credit from your utility company for that surplus energy.

Homeowners in some states receive full retail rate credit for the amount of surplus energy you send back into the grid. In Missouri, you receive credits at an avoided cost rate for the amount of surplus energy you generate.

Avoided cost rate is the amount it would have cost your utility company to burn coal or gas at one of its plants to generate electricity. Avoided cost rate is going to be less than a full retail credit, but as a Missouri homeowner you still receive credit for the excess energy your home’s solar system generates.

The state of Missouri requires all utility companies in the state to offer net metering to customers with solar power systems up to 100kW. You receive a credit on your monthly utility bill at the minimum of that utility company’s avoided cost rate.

Missouri Property Tax Exemptions for Solar Homeowners

Installing solar panels to your home will increase your home’s value by several thousand dollars. This is due to the substantial energy savings you will receive over the life of your solar power system.

All homeowners in Missouri are exempt from additional property taxes due to installing solar panels on their homes. Missouri does this to encourage homeowners in their state to take advantage of the cost savings from going solar.

Missouri Solar Rebates

Homeowners in the St Louis metropolitan area can take advantage of solar rebate programs that their local utility companies provide.

Ameren Missouri Solar Rebates

Ameren Missouri offers its own solar rebate program to help homeowners who want to go solar. Solar rebates are based on the size of your system and funds are available for solar rebates at $0.25/watt for Ameren customers.

If you are an Ameren customer in Missouri, you can submit an application for their solar rebate program on their website.

DSIRE Incentives Database - Missouri

The Database of State Incentives for Renewables and Efficiency (DSIRE) is a comprehensive database that Missouri residents can use to search for and find solar energy incentives in Missouri and across the entire country.
