Peter’s extensive design and engineering background has also led him to incorporate solar power into his designs. He did this with a focus on integrating solar thermal and solar PV into a roof cavity to create a more aesthetically pleasing look. He currently has two patents on his designs and has SRCC approval on one of them.
Utilizing extensive design and engineering experience, Peter has developed home designs which are cost-effective by utilizing cutting edge materials and building systems.
- Designs provide premium livability and curb appeal and can be completed to all finish levels.
- All homes provide the builder and the owner initial and long term costs savings by minimizing waste and maximizing insulation and energy efficiency.
- We optimize space inside the home and extend it to the entire lot utilizing glass and open spaces.
Through the use of a water fired water chiller, driven by solar generated 195°F water, summer air conditioning Is generated without an electrical compressor , using a lithium bromide refrigeration cycle. Either 510 heat pipe solar thermal vacuum tubes in the non concentration configuration, or 306 tubes in the concentrating configuration, are mounted in the south facing roof behind a skylight of 1/8″ clear tempered glass. The solar irradiance heats water in the manifold of the vacuum tubes to 195°F. This heated water is stored in a 500 gallon tank mounted above the tubes inside the attic space at the peak of the roof. No pumps or controls are required, since the tank is above the highest point in the vacuum tube array and circulation is generated by gravity whenever the water in the tube manifold is hotter than the water in the tank using a process called “thermosyphonation”. When there is not enough sun to heat the vacuum tubes, the circulation automatically stops, and the heated water is stored in the thermally insulated tank.
When the house thermostat calls for cooling, a pump transfers the heated water in the tank to the chiller, which produces an output of 45°F, which is passed to air handlers, which pass the cooled air to the rooms. At night or on cloudy days, when the temperature in the tank goes below 160°F and the thermostat still calls for cooling, a tank-less gas or oil water heater heats the water back to 195°F to resume cooling the house.
Measurements with the solar thermal vacuum tubes show that 350 tubes in the non-concentrating configuration of 10 tubes per 36″ wide bay, will provide enough thermal energy to operate the chiller, generating more than 3 tons of cooling. Therefore, the 510 tube capacity of the roof will guarantee that the chiller will drive the chiller unit with no back-up in most conditions when the sun is out. In the winter, when heat is called for, an automatic valve switches the water in the tank directly to the air handlers and the house is heated with any stored water temperature above 110°F.

The Structural Solar Roof Panel (SSRP) is an alternative to conventional building methods. It integrates the solar product into the building’s initial design and budget. Solar no longer needs to be an afterthought.
Energy Efficient High-Density Urban Development
With the patent pending structural solar roof systems and thermal wall systems that Peter Cummings has now developed, planned urban communities can now be energy producers with the possibilities of producing all of their own heat, air conditioning and a good portion of their electricity. In particular low income developments will have an impact on personal monthly budgets.

Estimated System Energy Generation
The roof shown in Figure 1 contains nine 36″ x 120″ bays of hybrid solar modules. Each module generates approximately 120 watts of peak electrical power at noon for a solar irradiance of 1,000 watts/m2 . Conservatively assuming 6 hours of full sun as an average sunny day, the photovoltaic cells should generate 9 x 120 x 6 hours = 6.5 kilowatt-hours per sunny day, and approximately 1 kilowatt-hour per cloudy day.
- Our Structural Roof Panels (SRP’s) will arrive in containers at the job site(s) fully assembled
- The panels can be fully installed by a basic construction team utilizing a small crane to lift and place the SRPs
As soon as roof panels are in place, one plumber/electrician can connect water and electrical connections using basic plumbing connections to the house’s utilities.
