SPP enters the solar photovoltaic panel market with the introduction of several new PV solar panels:

180 watt solar panel - UL Listed (Final, Feb 2009)(non-stock)
200 watt solar panel - UL pending (Due date -Feb 2010)
230 watt solar panel - UL pending (Due date - Feb 2010)
200 watt solar panel - UL Listed, Made In USA (out of stock)

270 watt solar panel - UL Listed
In USA warehouse - ORDER NOW!
(In Stock)

The solar panel market is driven by supply and demand, and as silicon wafer and cell shortages come and go, price fluctuations on finished solar panels occur. Currency exchange rates also contribute to pricing irregularities. Like all solar panel manufacturers, SPP PV solar panel prices fluctuate somewhat based on the conditions mentioned. Contact us for a firm quote - you will find our prices on solar panels to be VERY competitive.

SPP purchases the solar cells both under contract and on the open market, and has them delivered to our factory. At our factory the cells are tested and incorporated into the manufacturing process, resulting in finished solar modules (panels). The solar panel to the right is made from twelve rows each containing six monocrystalline cells. A total of 72 5" cells were used to make this 180 watt solar panel.

SPP solar panels are tested and listed by certified NRTL laboratories to Underwriters Laboratories UL 1703 standard for photovoltaic panels. That means the panels are safe and comply with the National Electric Code (NEC), OSHA, the National Fire Prevention Association, and will be readily accepted by local inspectors. The UL 1703 standard also means that the performance of the panels has been tested and has been found to perform to at least 90% or more of the manufacturers stated power rating. Most if not all of our panels are also tested and listed to the CE specifications allowing their use across Europe. UL 1703 is scheduled to eventually be superseded by UL IEC 61730, SPP solar panels will comply with the new standard. Our new 225w panel is already certified under IEC 61730.

There are many misconceptions regarding photovoltaic solar panels. An important one relates to efficiency - you should note that there is no practical difference for most users between a 16% and a 20% efficient solar panel. The less efficient one will take up a few extra square inches of rooftop compared to the more efficient one, but may cost far less per watt. Unless you have an extremely tight installation fit, you may be way ahead of the game to select a solar panel that is a few percent less efficient and save hundreds or thousands of dollars on your installation. SPP builds various sizes and efficiency levels of solar panels to suit our customers needs. Another misconception regards output. A "200 watt" solar panel will produce peak power of 200 watts (per hour) but depending on sunlight conditions (called "insolation value") and temperature the solar panel may produce more or less peak watts than during test conditions. A good way to estimate the total daily production of a solar panel is to multiply the peak watts by the insolation value. While this is just a rule-of-thumb calculation, the results will typically fall within 5% of a complete calculation, after accounting for inefficiencies. A good chart of national USA insolation values is shown below.

Use Solar Panels To Run Your Electric Meter Backwards With Net Metering

Net metering means that the power company (utility) is required to accept electricity from your solar electric system to offset purchased electricity. This means that at times when you are able to produce more solar electricity than you are using, the excess is fed back into the utility company power grid, for later use and offsetting your total or "net" monthly consumption or charges. This allows you to use the grid as a battery. Most state regulations do not allow to to have a negative net balance, so it may not be possible to have a utility cost below zero (a situation where the utility company would have to pay you).

Net metering is allowed in most states.
