With the incredible drop in price for PV solar systems, more and more people are adding them to their rooftops on a daily basis. Not only have the panel prices come down about 50% in the last five years, but the electronics have also dropped in price as well. In addition to that, many municipality’s have adopted streamlined approval systems to get people on a fast-track towards adopting this green, environmentally friendly, energy source. Many experts are now estimating that 25 counties in the UK will reach grid parity in the year 2017, without subsidies. There are many cost benefits, and a few problems, to be aware of when getting your own solar system, let’s take a look at those now.
One of the best benefits of going with PV solar panels is the incredible cost savings that you can enjoy. In many parts of the United States today, electricity can be very expensive, but there’s plenty of sunshine, and in these locations it’s quite possible that it is cheaper to install solar panels. One of the first things you’ll want to check, is whether or not your state offers any kind of rebates or tax incentives for solar installation. If you’re having trouble finding the information, your local solar panel installation company will have all the facts available, and be happy to provide them to you. They’ll be well versed on any rebates or tax advantages because they use them in their sales pitch and help their clients obtain them after installation.
It can be argued that the most important reason to install solar panels on your home is to reduce your carbon footprint and help save the planet. In many parts of the US where they use coal primarily to generate electric power, the power companies are pumping many millions of tons of carbon dioxide into the air, along with hundreds of toxic chemicals and a few heavy metals such as poisonous mercury as well. The cost to humanity in sickness and death from these tons of pollutants is difficult to measure, however, nobody has ever died or gotten sick from a solar spill. There is enough sunlight hitting the planet earth every hour to apply all of the power needed by humanity for an entire year, if it was able to all be harvested.
Another, often overlooked, advantage of solar is that when the lines are down you’ll still have electricity in your home. As batteries for solar systems come down in price, many homes in particularly sunny locations will be able to completely disconnect from the grid and never look back. However, it is also an advantage to be able to sell your extra power on the sunny day, back into the utility company’s grid and earn credits to be used on the next cloudy day.
As far as disadvantages go, right now the biggest disadvantage is the lack of economical backup batteries. This doesn’t mean that you can’t install a high-quality PV solar system in your house now, and add to it with a battery system in the future. There are many scientists and researchers around the world making breakthroughs in battery storage every few weeks. Just a few of the right breakthroughs could mean long-lasting, inexpensive storage, for all your extra solar generated electricity forever.
As you can see, there are quite a few advantages to installing a solar system on your home in many parts of the world today. As prices drop further, more areas will become cost-effective for the installation of solar and eventually help save all of us from the coming high tide.
