Methodology: How We Ranked the Best Solar Companies in South Houston
EcoWatch's solar experts analyzed each solar company in South Houston based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in South Houston
Below are some the criteria we examined specifically for Texas solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in South Houston
Although solar panels can help save you money on energy over time, it’s important to consider the upfront costs.A few main factors that influence how much it will cost to install solar panels on your home and how much it could save you over time are:
- Average daily sunlight: Since South Houston gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which impacts how much you can save on your energy bills.
- Incentives: Tax-paying citizens who install a solar energy system this year can save 0 of their overall solar costs by using the federal solar investment tax credit. You can also save about $19,000 on your energy bills over 20 years without incentives.
- Choice of solar panels: The kind of solar panels you want will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
- Energy consumption: Installing solar panels may be a high-cost investment for households that don’t use too much energy per month.
As a result of solar panels now being cheaper than ever as well as local and federal solar incentives, they are a worthwhile investment for many homeowners.
