SOLAR PANELS
Using grid-connected PV power can have economic as well as environmental advantages. Where utility power is available, consumers can use a grid-connected PV system to supply some of the power they need and use utility-generated power at night and on very cloudy days. When the PV system supplies power to the grid as well as to a specific building or piece of equipment, the utility becomes a storage device or battery for PV-generated power.
Homeowners that have sizable PV systems connected to the utility grid like that the system reduces the amount of electricity they purchase from the utility each month. They also like the fact that PV consumes no fuel and generates no pollution.
The owner of a grid-connected PV system can often sell as well as buy electricity each month. This is because electricity generated by the PV system can be used on site or fed through a meter into the utility grid. When a home or business requires more electricity than the PV array is generating (in the evening), the need is automatically met by utility power. When that home or business requires less electricity than the PV array is generating, the excess can often be fed (or sold) back to the utility through net metering, which is becoming more and more common throughout the nation. At the end of the month, a credit for electricity sold is deducted from charges for electricity purchased.
Solar Air Collectors
Have you ever gotten in your car on sunny day while it was a bone chilling temperature outside and noticed that it was nice and toasty warm on the inside of your car? Now imagine a system that is designed to harness that energy and redirect it in to your home or business.Solar warm air systems work on the same basic principles as Solar Water Heaters except the medium they use is air instead of a fluid. A flat panel is mounted to the south side exterior of your home or business (or can be roof mounted). The panel collects the energy from the sun and then the warm air is fan forced through the top of the system in to room to be warmed or moved in to the
Solar Air Collectors use the sun's energy to heat cold outside air for use in buildings. In doing so, they reduce the amount of space heating needed to keep buildings comfortable on cold days. Since about 13% of the energy we use in the United States goes to heat homes and commercial buildings, this new technology could result in significant energy conservation, saving millions of dollars in heating costs in the process. And because Solar Air Collectors dramatically reduce utility bills, they can literally pay for themselves in just a few years.
This new technology provides an effective means for substituting renewable energy for fossil fuel consumption, particularly in cold climates.
Solar Air Collectors use a simple, elegant technology to capture the sun's heat to warm buildings. The collectors consist of dark, perforated metal plates installed on a building's south-facing wall. An air space is created inside the collector. The dark outer face absorbs solar energy and rapidly heats up on sunny days — even when the outside air is cold.
A fan or blower draws ventilation air either from the outside or cold air return from the heating system or building and up through the air space within the collector. The solar energy absorbed by the collector warms the air flowing through them by as much as 40° F.
Unlike older space heating technologies, Solar Air Collectors require no expensive glazing, which caused energy loss due to reflection. The lack of glazing, together with design refinements, allow the new collectors to capture a record-breaking 80% of available solar energy.
Advantages
Solar Air Collectors have many advantages. They are the most efficient solar collectors in the world. They pay for themselves quickly and produce environmental and economic benefits with no negative side effects. They are suitable for any home or large commercial buildings.
Solar Air Collectors are virtually maintenance free and contain no moving parts other than the ventilation system fans. At night, they reduce the amount of heat escaping from buildings by recapturing heat lost through the building wall behind the collectors. Solar Air Collectors also help improve indoor air quality because good ventilation is an integral part of the system.
Solar Air Collectors are versatile. They can be added to existing buildings or designed as part of a new building's facade. They pay for themselves even faster when installed in new buildings than when they are retrofitted to existing ones.
Solar Air Collectors are easier to use, cost less, and are more efficient than older solar air collectors made with glazing. Their installation is simple. They require fewer materials. And they absorb more solar energy, making them more efficient.
Solar Air Collectors reduce the amount of energy needed for space heating in cold climates. Lower energy requirements translate into reduced building operation costs and less reliance on fossil fuels such as natural gas, heating oil, and coal. To the extent renewable energy replaces fossil fuels, there are fewer emissions of pollutants and greenhouse gases.
Disadvantages
There are few disadvantages to using Solar Air Collectors. However, some multistory buildings have fire codes that make transpired collectors impractical. Existing heat-recovery systems in some buildings may also be incompatible with Solar Air Collectors.
Applications
Solar Air Collectors are recommended for residential, industrial or commercial buildings. They work best in sunny locations on buildings that have a large south-facing wall for mounting the collector(s). They have the greatest impact on heating costs in regions with long heating seasons and high fuel prices.
Solar Air Collectors are easily combined with most standard ventilation systems in existing buildings. Collectors can also be designed as part of a new building's facade.
Solar Air Collectors are an affordable option for many buildings with high space heating costs that do not currently heat outside air for indoor use. They are most cost effective in buildings with a south-, southeast-, or southwest-facing wall; in colder climates; in buildings with high utility rates for heating.
Both the public and private sectors use Solar Air Collectors to reduce building heating costs. Ford Motor Company, McDonnell Douglas, General Motors Corporation, and Federal Express are some of the private companies that use Solar Air Collectors to help heat buildings. Common applications include homes, manufacturing plants, apartment buildings, vehicle maintenance facilities, hazardous waste storage buildings, gymnasiums, airplane hangars, schools, and warehouses.
Solar Air Collectors can also preheat combustion air for central-heating plants or industrial furnaces.
SOLAR HEAT
The SolarSheat 1500G panel heats inside are. The amount of heat produced is based on the volume of air passing through the solar panels and the degree of sunshine. The Solarsheat is a supplemental heating system. It does not work at night. No A/C electricity is required to run the system.
Roof Mounting
The SolarSheat 1500G panel heats inside are. The amount of heat produced is based on the volume of air passing through the solar panels and the degree of sunshine. The Solarsheat is a supplemental heating system. It does not work at night. The inline fan kit can be powered by an AC/DC wall adapter or with an additional PC cell, to keep it off the grid.
1. Does the SolarSheat provide heating for my residence?
Yes, one SolarSheat 1500G or 1500GS provides supplementary heating for a room up to 1000 square feet (in a well-insulated house, in northern US, or southern Canadian climates).
2. How does the Solarsheats work? What does it do?
It's an air heater that mounts on the outside of a south facing wall or roof. The sun heats up a SolarSheat air collector like the sun warms your car on a sunny day. Imagine capturing that hot air and dumping it into your home during the fall, winter, and spring heating season (see the How it Works diagrams on each product's page).
3. What is the difference between the SolarSheat 1500G and 1500GS?
Both Solarsheat air collectors use inside air and heats it up to higher temperatures, and dumps it back into the house. The 1500G uses a self-powered fan, which is built into it with a solar electric panel. It's designed to be installed very quickly. It can be installed in 1 hour on a south facing wall. The 1500GS is considered a "secondary" solar collector, with no moving parts. It was designed to add power to a 1500G (see 1500G 2 Pak) or to be connected to other 1500GS's.
4. Does the SolarSheat have storage capability for nighttime use?
No, the SolarSheat only works during the sunny day time hours.
5. Aren't liquid solar collectors better?
They are about 10-20% more efficient, but liquid solar thermal collector (flat plate, evacuated, etc.) systems are much more expensive. Try to heat anything for $1799 CAD/ $1685 USD (retail, price subject to change) and 1 hour of installation time by a typical handy home-owner (see our 1500G self-powered air collector). No leaks, no worrying about glycol ratios, anti-freeze pH balance, rust inhibitors, stagnation damage to antifreeze, power outages, overheating solar storage tanks during vacation time, or steam filled basements, heat exchanger or collector calcification (non-anti-freeze systems). Check out our SolarSheats. It just doesn't get any simpler, more reliable, and less expensive in any other solar heating system.
6. How long does the SolarSheat take to pay for itself?
Multiple SolarSheat 1500GS takes about 6 years to pay for itself (DIY install, Toronto's climate, 10% annual utility escalation, Oct thru April heating season).
7. How much sun do I get?
In most North American climates, the average sunlight of a heating season occurs in October and February. Imagine the sunlight in October and February in your location, 50% of the time it's sunnier, 50% it's darker (see the Solar Map link, in the Links section, for more details).
8. Are there goverment subsidies available?
There is PST exemption for any solar technology purchased. A Canadian government subsidy called REDI is available for commercial installations. You can get 25% of the amount back for commercial installations. There is an agreement and proposal that needs to be completed and approved. The United States has different subsidies for each state. Only some states have subsidies. The U.S. has announced the new solar tax credit effective January 1, 2006 through December 31, 2007. (see the incentives in the Products section)
9. How does the SolarSheat product work with an HRV?
We use a specially designed HRV to work with our Solarsheat 1500s panel system. The fresh warm air is collected and passed through the HRV. The heat exchanger inside the HRV is only used during the non-sunny days or nighttime (see the Solar HRV in the Products section).
10. What's the best collector tilt angle?
The best solar collector tilt angle (from horizontal) for space heating is equal to your location's latitude + 15 degrees. However collector tilts equal to your latitude to 90 degrees (wall mount) is generally acceptable. When there is snow is often on the ground in front of the collector to reflect sunlight onto the collect, then mounting on a wall (90) is especially great. Wall mounting collectors is generally the least expensive, especially for adjacent, direct room heating, but is the most susceptible to shading. For roof mounts, to shed snow, we recommend an angle no less than 40-45 degrees (aka. 10:12 to 12:12 pitch), no matter what your latitude is (see the Latitude Finder link in the Links section).
