Solar Panels & Cells

What is the efficiency of PowerFilm modules?

There are many factors that go into the how much power you are able to draw from your solar panels, and many are related to the design and orientation of your solar array. With that in mind, a safe average to assume with PowerFilm technology is 5%. Flexible panel technology, however, is still young compared to rigid panels, and as such is advancing all the time. There are widely varying standards within the industry for solar panel efficiency ratings...


How many watts do solar panels produce?

The number of watts that a solar panel produces depend on different factors, for example the watt-class, the shading of the solar panel but especially the location in which the solar panel is installed. Solar panels will produce more watts in very high irradiated areas, areas that have a lot of sun light, than in low irradiated areas. For instance, a 100 watt solar panel during a bright and hot afternoon, in a highly irradiated area, the solar panel...


Can I charge two batteries at the same time?

Yes you can, but you need to connect the battery in parallel connection (and to set the expectation if you load many batteries the charging time will increase).


How to clean off the solar panel?

You can use vinegar to clean off the solar panel (every year it good to clean the solar panel, takes 2-3 min).


What is a solar power inverter?

The solar panels on your roof absorbs sunlight and produces DC electricity. The DC electricity is then sent to the solar power inverter. The solar power inverter converts the DC electricity into AC electricity. The solar power inverter then sends the AC electricity to the electrical panel where it is then distributed to power your household appliances. In short the solar power inverters are what coverts the DC electricity generated by the solar panels to AC electricity, the electricity...


What is the ideal operation temperature for the PowerFilm series?

The PowerFilm series is designed to operate in all atmospheric conditions, though the optimal operation temperature is around 75°F. Every panel gets less efficient as its temperature rises far above 80°F


How would I go about extending the length of cable from my battery to the solar panel for my Aquajet kit so I can place my panel somewhere farther away?

You will need a 14 gauge wire with positive and negative terminals inside, and a basic knowledge of soldering. Wire can easily be spliced anywhere in between the connection from the solar panel to the battery box. Wire should not exceed 50 ft. in length at 14 gauge to minimize the voltage drop to below 3%. If you require the panel to be even farther away than this, the wire gauge should be thicker to compensate for the distance...


How much electricity do solar panels produce in a year?

The answer to how much electricity solar panels will produce in a year is hard to answer because it depends on a number of different factors like weather, how clean the solar panels are, distance from the equator, what time during the day, shading and maximal output. But a very rough estimate for a 100 watt rooftop solar panel should produce about 240,000 watts a year.


What factors should I consider for installing a home solar system?

Is the place where you live very snowy or very windy? You should consider the climate of the area that you live in before installing a home solar system. It is important to understand how the climate will affect the use of your solar panels as it determines the type of mounts you might use and at what angles the your panels should be positioned. It would be a good idea to seek out a local solar professional for...
