Quick History on Solar Panels
Solar power is a fairly new technology, having only been around for a little over 60 years. Western Electric licensed the first commercial solar panel in 1956, but it was only about 6% effective and was too costly for most people. With research and the advancement of the technology, cost were driven down and efficiency was boosted. Solar panels for homes came around the 1970s and in 1995, some recreational vehicles became outfitted with solar panels. In 2005 solar panels were extremely affordable and DIY panels hit the market. There are even tax credits available to home owners that have solar power. This caused solar panels to became popular among home owners. With further advancement, there are now flexible, printed solar strips that are economical and easy to install.
Options to Add More Solar Panels
With solar panels being installed on so many homes and having better efficiency than ever, home owners are finding that they want to add more solar panels for increased energy needs. Home owners have three options for upgrading their solar panel systems:
- If the old solar inverter can handle more power, simply add more panels to the system.
- If the old solar inverter can’t handle more power, get a new solar inverter and more panels for the old system.
- Get a new solar inverter and a new system.
Either option will work in most cases, but the option you choose depends on the efficiency of your old system, how old the system is, and if you are able to find panels for that system.
It is definitely recommended to use the same installation company that you used the first time around. They will be familiar with your layout and probably will have the same equipment and the same brands that was used the first time around. Another thing to keep in mind is that switching to different installation company could void your warranty. If it isn’t possible to use the same company, you will have to call a new company or install the panels yourself. Make sure that they have good reviews and have the proper equipment and brands to match your existing system. There are a few steps that you can take to make installation easier:
- Check to see if you need to perform some solar cleaning. If your panels are dirty, this could be a reason that you aren’t getting as much power as you need. Most solar panels are self cleaning, but in some instances there could be dirt, bird droppings, etc. covering your panels, and this could impact the amount of power your system is absorbing.
- Make sure you have enough space on your roof for an extra rack of panels. If you don’t you can most likely install extra panels in your yard.
- Check the maximum power of your inverter. You can have peak power of up to 133% of the listed inverter power. If your inverter is already at maximum power usage, then you will need to install a bigger converter. If your system uses mini-converters, you won’t have to worry about the inverter as each rack will have its own converter and less wiring will be required.
Solar power is one of the best technological advancements in the world. It is helping to reduce our carbon footprint and saving people money on energy costs. With other technological advancements, people are adding more electronics to their homes, creating a need for more power. Adding more solar panels is the best solution since the power source is infinite. It is possible to expand an existing system and by using this guide you can have an quick, easy, painless upgrade.
