FAQ

Yes, solar panels can be installed on a pergola or shade structure. In fact, this is a popular option for homeowners who want to maximize their solar energy production while also providing additional shade and functionality to their outdoor space. The pergola or shade structure can serve as a sturdy and aesthetically pleasing platform to mount the solar panels, allowing for dual benefits of energy generation and outdoor comfort.

The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.

Yes, solar panels can power an entire home. The number of solar panels required will depend on the energy needs of the home and the efficiency of the panels. With the right setup and sufficient sunlight, solar panels can generate enough electricity to cover the energy consumption of a household.

What direction do solar panels usually point? North? East? South? West?

The general answer is toward the equator, so south when the array is north of the Tropic of Cancer, and north when south of the Tropic of Capricorn. In the equatorial zone, one would often still point towards the equator, but other factors such as wanting the panels to efficiently drain rain and dew come into play. But wait, not so fast. Financial considerations dominate in some areas. When afternoon electricity costs more than morning electricity, it may pay to have panels oriented southwest in the northern hemisphere. Where electricity costs the same all day long, it may pay to orient the panels southeast, to harvest more in the morning, when temperatures are cooler, and the panels are more efficient. For solar hot water, SW is usually optimal in the northern hemisphere, because of higher ambient temperatures, and also the usage pattern of most people using the hot water when they get home in the evening. A local installer that has been around for several years will know what orientation is optimal for your area.

Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.

Solar panels can have a positive impact on the resale value of a home. Studies have shown that homes equipped with solar panels tend to sell faster and at a higher price compared to those without. This is mainly because solar panels offer potential buyers the benefit of reduced energy costs and a more sustainable lifestyle. Additionally, the presence of solar panels can enhance the overall appeal and desirability of a property in today's environmentally conscious market.

Yes, solar panels do require regular inspections and maintenance checks to ensure optimal performance and longevity. These inspections typically involve checking for any potential damage, dirt or debris accumulation, and monitoring the efficiency of the system. Regular maintenance checks may include cleaning the panels, inspecting wiring and connections, and testing the functionality of inverters and other components. By conducting these inspections and maintenance checks, any issues can be identified and resolved promptly, maximizing the efficiency and lifespan of the solar panel system.

i have a 50 watt 2 Volt solar panel..Will it can switch on directly a car head light on a sunny day??? How much head lights it can support on a bright sunny day??? if its cloudy then can it run a single Head light???? i have no batteries just want to connect a car Head light directly to solar panel.

it should power 2 55/60W 2V headlights, at full output. But it may be less, depending on the brightness of the sun, and the length and type of wire used.
