If you want to buy solar panels, you most likely want to connect them to the grid. But there are some homeowners and others who want to be or need to be off the grid. There are the folks who have a cabin in the mountains and there is no grid anywhere close by. There are the farmers in Northern California who are growing, well, let’s just say they don’t want anyone to know how much electricity they are using. There may also be some homeowners who are on the grid but want a battery back-up system for emergencies or natural disasters. For these solar energy users, getting the right home solar panels is the easy part. The critical component of their off grid solar energy system is the solar battery. Choosing the correct solar batteries and understanding how to maintain and take care of them can be a challenge. In a recent series of learning articles, we have tried to demystify solar batteries.

A couple weeks ago, I spent a lot of time overheating in my dark, humid house with fond memories of air conditioning to to keep me company. Ironically, this year’s Independence Day reminded me of just how dependent I am on grid power. Without it I lost AC, water, and several hours of each day. I know I wasn’t the only one this happened to. This year’s power outages affected hundreds of thousands of people and in Virginia almost one million households lost their power. My home does not have a backup generator and, until recently, was only stocked with just one flashlight. In hindsight this was not a good decision. Since we as a nation probably won’t upgrade our infrastructure, power outages are going to continue to happen. This is especially true considering that some scientists have linked extreme weather last year to climate change. In order to be more prepared for the next outage I’ve decided to get a backup system. I have two main choices: diesel and solar.
We changed gears somewhat this week and attended the Sixth Annual Aid and International Development Forum (AIDF) being held here in Washington D.C. Some of the manufacturers whose products we represent at SolarTown such as Voltaic Systems with its solar bags and Sun Danzer with its solar refrigerators were there to show how their products have an important role to play in helping countries develop and saving lives. You don’t believe that solar fridges can keep critical medicines safe. Well, think again, as this solar vaccine refrigerator has been pre-qualified by the World Health Organization and has undergone rigorous testing. There are many other applications of solar energy to the developing world such as solar lights and solar battery chargers, which can provide a lifeline to those living off the grid throughout the world.
My family installed a solar energy system in rural Brazil twelve years ago. A little bit of social consciousness and a lot of economic reasons persuaded us that solar energy was the way to go for our home in Minas Gerais in the interior of Brazil. This is our first-hand account of how and why we went solar. Access to the house was and still is restricted to one dirt road. At the time, there was no electricity, since power lines stopped several kilometers away from us. For the first two years, kerosene lamps lit our lives at night. The electricity grid was not and has not been extended, despite our good efforts. In 1999, we decided to buy the property and install home solar panels to replace the kerosene lamps, radically transforming our electricity consumption there. For twelve years, solar energy has provided us with reliable electricity in the temperate rainforest in Brazil. Lack of infrastructure, a need for electricity and a desire to do the right thing toward the community convinced us to install solar energy in this rural and remote place…and the cherry on top is that we have never and will never receive an electricity bill in the mail.
