Solar Company Ranking Methodology

The Cost and Benefits of Solar in St Louis
When picking a solar company, most homeowners or business owners wonder about the costs above all. The installation cost is just one important factor you should keep in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state and even local utility companies may also have incentives and rebates that you can use. Plus, you can save about $17,000 over 20 years on your utility bills, without incentives.
- Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
- The amount of sunlight your roof gets: Because of St Louis' high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.
- Typical energy usage: The more energy your home consumes on average and the greater your current energy bills are, the more benefits you'll see from going solar.
So are solar panels worth it? Whether you're trying to decrease your electricity costs, carbon emissions or both, solar panels are a good investment for many St Louis homeowners.

Solar Incentives in St Louis
If you're thinking about switching to solar energy, various government incentives and tax credits can drastically bring down the cost of the project and speed up the return on your investment. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 30% of your project costs on your tax return, reducing the amount of taxes you owe that year. In addition, there may be some local incentives you can benefit from too. In our article on solar incentives, you can read about the incentives you qualify for in your area.
Environmental Impact of Switching to Solar in St Louis
One of the most compelling reasons to embrace solar energy is to minimize your dependence on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment. Something many people might be wondering about is how much can they really help the environment by going solar anyway? If your family uses lots of energy, you can help the environment even more by switching to solar power. Since solar panels don't release greenhouse gas emissions into the atmosphere when generating electricity, they're a good trade for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 100 pounds each year. For those who want to help the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.
