Freedom Solar Power installs American-designed solar panels that are built to last at least 25 years. We like that it has an in-house staff of NABCEP-certified installers and licensed electricians. It doesn’t subcontract work out to local companies like some of the big national solar energy providers. Sunlux stands out for its competitive pricing, good customer service and quality solar panels. Its 24/7 monitoring app lets you easily track your system’s performance, and tech support is on standby if anything goes wrong. We also like that Sunlux can take care of any necessary roof repairs or replacements before installing your system .
