How We Install REC Solar Panels

As a Certified Professional Installer, Design My Solar Power is proud to partner with REC Solar, a leading European manufacturer with a 25-year track record of innovation, making 4 million panels annually in Singapore.

We mount these panels on the low-profile, all-black Pegasus Rail racking system, which has the industry’s thinnest gap between the solar panels and the roof, ensuring a sleek-looking system.

REC Solar panels are installed with EnPhase microinverters or a Tesla Powerwall 3 solar battery with an integrated inverter. Your inverter will determine the monitoring system you use.

When you schedule a consultation, we will meet with you to understand your goals and to review your roof and electricity usage. During that appointment, we will recommend the equipment that best meets your needs for your home installation.

Product FAQs

Independent reviews of solar panel manufacturers confirm that REC makes one of the highest quality, high performance, most durable home solar panels in the world.

With decades of experience you can trust, cutting-edge manufacturing in Singapore, innovative solar technology, and a comprehensive warranty, REC makes some of the best solar panels on the market today.

The REC ProTrust warranty, which is only available through REC Certified Solar Professional installers for registered panels and installations, covers product, performance, and labor.

Customers with installations up to 25 kW enjoy maximum comfort and peace of mind knowing that they have a full 25-year warranty covering product, performance (at least 92% of rated performance in year 25), and labor. Systems between 25-500 kW have the same 25-year product and performance warranties, plus a 10-year labor warranty.

The industry leading ProTrust warranty makes it easy to get service, but with the lowest warranty claim rate of any manufacturer, you probably won’t need it.

The cost of installing REC solar panels will vary depending on your electricity usage, property size, and the type of inverter and other equipment you use. Our team at Design My Solar will provide a personalized estimate at no charge.

In addition to the upfront price of the system and energy savings over time, you will also want to consider the total cost of ownership of the system. Products that generate more electricity over time, stand up to harsh conditions without breaking, and have a warranty with the cost of labor and service included, will save you more over the life of the system than the price premium you may pay upfront.

We’ll assist you in evaluating your options, selecting the right equipment for your needs, and maximizing available incentives and tax credits.

We also offer easy financing options, including $0 down and low monthly payments tailored to your financial situation.
