FAQ:What's products warranty?

No less than 90% within 10yrs and no less than 80% within 25yrs

Q: I heard that solar energy has a lot of advantages but are there any drawbacks in using the solar panels?: The largest drawback is the upfront investment you have to make for solar panels. There are some programs that allow you to finance the panels through your property assessment called PACE and leasing programs that can alleviate the large upfront cash outlay. Solar Panels have a lifespan of 30+ years. Since there are no mechanical parts, there is very little maintenance required. After 0-5 years, you will have to replace the inverter which converts the energy from DC to AC. This is a small cost in respect to the whole installation. The panels clean themselves well with just normal rain. With all the great federal and state incentives, the payback on solar is at it's all-time best. In Massachusetts, for example, the payback right now is 5 or 6 years -- then you would be making money for the next 25+. Another big potential drawback is that you must have the right site for solar to begin with. I'm a solar installer and I can tell you a lot of houses might not be right for solar. The best orientation is south, while southeast and southwest can work as well. The space must be unshaded and it would be best if it had few obstructions like chimneys, etc.

Q: what do I need to do to disconnect a solar panel from a battery to protect the panel?: Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.

Q: Can the solar panels available be coated with a material (to improve it's looks) and not alter it's efficiency?: No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.

Q: I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?: This Site Might Help You. RE: how long do roof solar panels last? I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?

Q: Can solar panels be installed on a swimming pool?: Yes, solar panels can be installed on a swimming pool. These panels can be used to heat the water in the pool, reducing the need for traditional heating methods and saving energy costs. Additionally, solar panels can also be used to power pool pumps and other equipment, making swimming pools more energy-efficient.

Q: Can solar panels be used for powering traffic lights?: Yes, solar panels can be used to power traffic lights. Solar panels convert sunlight into electricity, which can be used to power various devices, including traffic lights. This allows for a sustainable and renewable energy source for traffic signals, reducing reliance on traditional power grids and minimizing environmental impact.

Q: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.: A solar panel to charge a 2V battery has 36 cells in series. This allows for temperature of the panel up to 60°C, and the maximum required charge voltage. For a 24V battery, 2 panels in series. A 24V battery requires around 28-29V, but look up your battery data sheet to be certain. A specialized converter using electronics could charge a 24V battery with a 2V panel. The system voltage is controlled by the battery unless the battery is faulty. The 2 panels in series could be 42 volts no load, but the battery pulls this down to whatever is required by the battery. This is because the panels are a current source, the current is determined by illumination, and attempts to draw more result in reduced voltage. Even a short circuited panel delivers approx. the same current with no voltage. The battery voltage varies from around 20V (really flat) to around 28V (really charged). A 30W panel is around .75A, considering the optimum panel voltage for power is around 7V for 36 cells. This is small compared with what you are using. The battery wastes about 30% of the power, in chemical conversions. The time to charge it is 4h at the 0h rate, which is Ah/0. (i.e. ampere hours)

Q: Is it possible for a 2V rated panel to charge a bank of batteries equal to around 36V? I believe that the panels should equal or exceed the voltage of the batteries but, I'm not for certain.: You're right. The solar panels must produce a voltage equal to or slightly greater than that of the batteries. So you need to either switch to a 2 volt battery or add two more solar panels of the same current rating.

Q: In nature, green leaves collect light and produce energy. Is this what they copied to make solar panels? If not how hard would it be to make artificial leaves that would power our homes?: Solar panels may have been inspired by leaves, by they don't function in the same way. Leaves use the sunlight to make carbon dioxide into carbohydrates. Solar-panels makes sunlight into electricity.

Q: My family moved into a house that came with solar power panels but they are not connected and don't really understand how to even begin.: You need to know some electrical basics. You need to check if they are still working and determine the output voltage with the use of testers. They are just part of a system that includes other equipments as well like a controller, car batteries, inverters, diodes.
