It’s no secret that, despite the long-term savings that it provides, going solar is an expensive decision. Installation costs will undoubtedly be an important factor when looking for a solar company. Additionally, various financing options and tax rebates will affect your overall cost. But at the end of the day, you’re much more likely to pay less by going with a local company. A study done by the National Renewable Energy Laboratory showed that larger installers charge about 10% more on average when compared to smaller, local companies, and that local companies will provide a lower quote roughly 70% of the time. Additionally, many companies will offer discounted rates when bundling solar with battery or roofing services.
