Connecting Solar Panels From Lamps

Obviously the series connection is less common for solar panel and batteries installation as the system will only increase the level of voltage from 12vdc to 24vdc which is only applicable in a 24v inverter system.

Connecting solar panels from lamps.

Connecting solar panels in series. This means instead of having two solar panels producing 6v and 150ma each we now have two solar panels working together to produce 12v 150ma. Just like a typical battery you may be familiar with solar panels have positive and negative terminals. Solar panels virtually any solar panel with an output of 5 watts or more will charge the battery but larger panels charge the battery more quickly and that s important.

Portable solar panels are today quite affordable so if you are seriously thinking about how to make your own solar powered string lights go for it as the idea will surely pay you back. The most common is the 12v system. Stringing solar panels in series involves connecting each panel to the next in a line as illustrated in the left side of the diagram above. The series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter.

For outdoor lights you can connect the battery directly to the lights to power them. A single solar panel isn t going to power indoor domestic lighting but it will be able to power a series of outdoor lights. A good modern option for low wattage outdoor lights is led lights. The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery.

If you have a 150 ah battery and get about eight hours of sunlight a day the panel output should be at least 120 watts to ensure the battery charges fully during the day. If we have two solar panels with the same voltage but different wattage there is no problem. They can be wired in parallel. On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the.

Pv panels and batteries are available in the range of 12 23 36v etc. For example a 110ah battery should never be connected to a panel more than 11w without a solar controller and if you are using a solar controller you do not need a blocking diode. By connecting the two serperate groups of solar panels in parallel we can make 1 big solar panel producing 12v and 300ma. Do the same with solar panels 3 and 4.
