The 15 Watt Solar Panel maintains your 12-volt battery to ensure many operating hours. You will have a trouble-free operation for various applications. Your battery will always be in tip-top condition.
The Renogy 15 Watt solar module kit also includes a 7 amp charge controller.
Proper maintenance of the battery ensures a much longer lifespan. The charge controller protects the battery from any surges as well as overcharging.
The amorphous solar module acts as a clean source of energy. By making use of it you will reduce your energy bill while you control the energy from the sun.
The total kit includes;
The Renogy 15 Watt 24 Volt amorphous panel is ready to generate cheap energy. Direct it to the sun and it is in operation.
Always remember to get peak wattage the sun must shine perpendicular to the solar panel.
The sun will do the job and the ultra-bright blue LED will show when charging. It indicates when finish and ready to use.
If you want to do a permanent installation you have to use the 4 stainless steel mounting screws. The screws come with the kit. The rubber washers are to use for spacers between the panel and the surface. This is to allow for heat dissipation.
If you now have a 5 hour period of sunlight per day the solar panel will produce 5 x 15 = 75watt per day.
Not enough to charge a battery, but more than enough to maintain it.

To store the energy it will eventually be necessary to get a proper battery.
Sizing the battery requires certain steps;
Watts from panel times sun hours x.85 due to 15% for losses.
That will be 15 x 6( Depending on the area you live.) x .85.
You get 90 x .85 = 76.5 watt
Round to 75 watt.
The DOD (Depth of discharge.) must not be more than 50% to ensure a long battery life.
We have to multiply the 75 x 2 to get 150 watt.
Divide watt by volt to get Ah.
This is 150/12 = 12.5 Ah.
A 15 Ah battery will be a good choice to store electricity for one day.
The only maintenance that you as a user have to do is making sure the cables are not damaged. This is to ensure a good working condition.
Cleaning the surface of the 15 watt solar panel is also very important. Use a damp cloth to perform this duty.
A dirty panel leads to a big drop in efficiency.
A professional person must perform all other maintenance functions.
The 15 watt solar panel and charge controller do what it says it will do.
It is a good quality solar module that is well constructed and affordable.
The module works great for the money.
