Tips

Christmas Lights on Solar? Why Not!

Yes you can do this.. and save more on your electricity bills during the holidays.

Use LED Christmas lights instead of the usual Christmas lights that you see at the malls/stores.

Here’s what you need
10 watts solar panel (or 5 watts)
5 watts 100 LED bulbs Christmas lights
50 watts inverter (or lower)

When daytime the solar panel will charge the battery. At night time the battery will power the Christmas lights, it’s that simple and the installation/wirings are very easy to do.

Solar Charge Controller – Why Do I Need It?

Here’s another guide on solar panel installation.

solarchargecontSolar Charge Controller – how important is this product to your solar power system.

A charge controller or solar charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and the current coming from the solar panels going to the battery.

Most batteries need around 14 to 14.5 volts to get fully charged.

Solar Power on a Budget

We’ve been getting a lot of inquiries from those who wants to install solar energy in their homes because they dont have electricity and some  they want to save money…

The thing is, most should understand that even though we can and will save money using solar energy, the solar panels are not that very affordable if you want to have your household appliances’ electricity all use solar energy.

When they realized that it’s costly to do that, they loose heart.

Well we have to start at something, and if we dont have that much money, then start at something small.  Especially if you are in a place where you dont have electricity, or if you’re electricity was cut down by meralco or in a place where there is always brown out.

Let’s say you dont have electricity and want to have lights at home, now this one… Continue reading
