Using the solar roofing technology originally developed by Dow Chemical Company, RGS Powerhouse Shingles are designed to provide roofing coverage similar to asphalt shingles, while providing homeowners with self-sufficient electricity generation. Unlike bulky solar panels, RGS Powerhouse Shingles are subtle and are more likely to blend into the roof.

Corporate History

Since the 1800s, scientists have been conducting experiments on the photovoltaic effect. It wasn’t until 1954, however, that the first solar cell was invented by Bell Laboratories, and a usable amount of electricity from the sun was generated by this scientific process. By the 1970s, solar cells were used on a number of buildings and became more widely known because of the energy crisis. In 1978, RGS (then known as Real Goods Solar) joined the solar energy market for residential solar installations. The 1980s saw a decline in solar’s popularity because of falling oil prices, but RGS remained in business. Since then, many advancements have been made in the production and efficiency of solar cells, and RGS claims to have taken part in many of these advancements. The company touts its veteran status in the industry, stating that it has been around long enough to see its products live up to their warranties. Today, the cost of solar shingles has dramatically decreased as installation of RGS Powerhouse Shingles has become more widespread. RGS Powerhouse Shingles have been installed on over 1,000 homes.


RGS encourages roofers to apply to be a Powerhouse installer. If accepted, roofers will undergo training on how to install the RGS Powerhouse shingles. In order to qualify to receive the training, roofers must already be licensed and insured, and they must have a reputation for quality roof installation. Knowledge of solar power is not needed, as RGS Energy will impart new installers with that information. The company encourages roofers to apply and as a result attract new customers, learn new technology, and make more money for themselves.

Product Lines

  • Solar Roof Shingles Overview: The RGS Powerhouse Shingles are an option for any homeowner seeking to replace their asphalt roofing or integrate solar shingles into their current roof. Unlike solar panels, solar shingles offer a much more discreet appearance. The Powerhouse 3.0 solar shingle is described as a fully integrated photovoltaic building product--meaning it can harness sunlight and produce energy while also acting as roofing coverage. The company claims that they offer the most cost-effective solar shingles on the market.
  • Durability and Effectiveness: RGS claims that their Powerhouse Shingles can withstand winds up to 200 mph and have earned awards and certifications on their durability. According to RGS, most solar shingles last up to 20 years and can pay themselves off in 5 to 10 years. They can also be more effective than solar panels because they’re made of amorphous silicon instead of glass. When light hits glass, it tends to break up and make absorption by the solar energy product more difficult. RGS claims that since their solar shingles aren’t built with the glass used by solar panels, their shingles are more energy efficient.
  • Installation: RGS Powerhouse Shingles can be installed with a roof replacement, or they can be integrated into an already installed asphalt roof. Stats: RGS Powerhouse Shingles are typically between 10 and 15 pounds per unit. Additionally, they produce between 10-75 watts of electricity which can lead to a 35-60 percent reduction in utility bills.
  • Sustainability: Like any solar energy product, the RGS Powerhouse Shingles allow homeowners to produce their own electricity without relying as much on coal, nuclear power, or natural gas. Furthermore, it provides homeowners with a self-sufficient method for electricity generation. During grid outages, homeowners with solar shingles may still have power on reserve from their solar shingles. If your solar shingles have generated extra electricity, you can sell that electricity to your local utility company and receive a monthly check in the mail.

Environmental Impact

The photovoltaic technology in solar shingles enables electricity to be generated from sunlight. Solar energy is considered a green energy because its use does not require the emission of harmful greenhouse gases like carbon dioxide. If you’re concerned about climate change, air quality, or the environment, solar shingles offer homeowners with the ability to “do their part” when it comes to consuming fewer fossil fuels. RGS claims that using their Powerhouse Shingles system for a year produces an average of 4800 kWh of electricity and is the equivalent of removing 7,296 lbs of carbon dioxide from the atmosphere. That’s comparable to planting 84 trees or not driving 7,880 miles in the average car.

In addition to offering solar shingles, RGS encourages homeowners to “go green” in other ways. The company offers brief information on installing a solar water heater, installing solar outdoor lights, installing solar or smart home appliances, and purchasing a hybrid or electric vehicle.

Additionally, in an effort to encourage sustainable practices, the US government offers a Federal Tax Credit on solar which can cover 30% of the initial cost of the solar shingles installation. Furthermore, many states and localities also offer rebates that homeowners can use to their advantage.
