Greenheart Solar engineers solar electric systems to accommodate a wide range of building styles and mounting locations. The design decisions, installation techniques, and use of quality materials maximize system performance, life expectancy, and trouble-free operation. Here are a few examples.

Location: Flat patio roof

System size: 2.4kW

The panels are mounted on a tilted frame anchored to the flat roof. The exact tilt and spacing ensures that no shading occurs.

To ensure the roof will last as long as the photovoltaic system (20 to 25 years), a white thermoplastic membrane roof was installed to replace the less durable asphalt roofing. The white roof also reflects heat and lowers patio and pool area temperatures.

Location: Tile roof (flat cement tiles)

System size: 4.8kW

This system publishes energy production data in real-time. Click here to access the dedicated web site and production statistics. For the system owner, statistics are also accessible from a cell phone.

This homeowner has also purchased a solar hot water system to reduce household energy demand.

During planning, three-dimensional models allow accurate visualization of the completed project, and ensure that no shading will occur at any time of year. If shading is predicted, the effects can be mitigated through equipment selection and wiring techniques.

Location: Tile roof (barrel cement tiles)

System size: 4.2kW

At this client site, the new solar panel array could easily outlast the existing tile roof. For this reason, an alternate mounting strategy was used: the tiles at the mounting site were replaced with a white thermoplastic membrane roof. This also helps keep the attic temperature down.

This homeowner has also taken steps to improve the home’s energy efficiency:

- Added supplemental attic insulation

- Replaced incandescent light bulbs with high-efficiency CFL and LED lighting

- Replaced the electric hot water tank with a solar hot water heating system

- Deployed a Greenheart Solar-engineered computer-based direct and supervisory control to manage select electrical loads.

Location: Multiple asphalt shingle roof surfaces

Total system size: 5.3kW

As a first step, an initial Grid-Tie system was installed. Later, a Battery-Backup (bi-modal) system was added to deliver extra capacity and to allow continued operation during grid outages. To leverage the existing investment, the initial Grid-Tie system was integrated to the Battery-Backup design.

This homeowner also installed a solar hot water heater to help reduce energy demand.
