About Terawatt Solar
who-we-are

WHY CHOOSE US?

Homeowners trust Terawatt Solar knowing we provide strong references from clients we have served for over a decade. Our clients will tell you that we continue to monitor and support their solar power installation long after their system is commissioned. We are currently offering eight years warranty on our installation labor.

WHAT WE DO

Unlike other companies offering a variety of products (eg solar hot water, solar PV, wind energy systems, gas/diesel generators, backup systems) we specialize in one product only: Rooftop Solar with net metered connection to the electrical grid. Unlike brokerage companies looking for the best contractor to do the work, we have everything in-house; we are not spending any time and resourcing for that, while the savings can be seen in our low prices.

WHAT WE OFFER

TeraWatt Solar offers the best installer warranty in the industry by guaranteeing our customers will see no expenses for the first 8 years after installation. Solar panels, racking and inverters carry manufacturer’s warranties of from 10 to 25 years. We source all equipment from tier 1 manufacturers. Their warranty covers the parts but liability often excludes labor to replace them. Our unique installer warranty includes labor so users can relax knowing there will be no additional costs. We help our customers apply for various incentives to help reduce the cost of your solar system such as Greener Homes Grant.
