Standalone solar panel technology (an off-grid solar power system) offers a great remedy for those unable to get linked with a local electricity system. They are also an option for people facing high grid connection expenses, or for those who are looking to be completely energy independent.
An off-grid solar power system expenses two to three times the price of a grid linked solar power system. While Complete Off Grid Solar Systems may sound enticing, it might not be the most practical solution if you can get connected to the grid.
An off-grid system is not attached to the electricity grid and therefore requires battery electricity storage. An off-grid solar system must be designed appropriately so that it will generate enough energy throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter when there is less sunlight. The costly price of batteries and inverters means off-grid systems are much more costly than on-grid systems and so are usually only needed in more remote areas that are far from any electricity grid. However battery electricity price is reducing rapidly, so there is now a growing market for off-grid solar battery systems even in cities and towns.
An off-grid solar power system is one that gets most or all of its electricity from the sun using a solar panel (photovoltaic panels) and none from an electrical utility such as a hydroelectric dam, nuclear, coal or natural gas-fired plant. The grid which is “off”, or refers to the complex system of utility grid that links the utilities to the numerous buildings that use the ability. Since in many locations there may be clouds for days or perhaps weeks at a time, DIY Solar Kits as well as off-grid systems usually have a backup generator as well. In addition, they may have wind turbines, micro-hydro and other small electricity generating means.
Maintaining an off-grid solar power system
Complete Off Grid Solar Systems are not plug-and-play. The solar panel needs to be kept clean, the generator needs to be kept fueled and to have its oil changed periodically, and the batteries need all sorts of maintenance to keep them working well and to have a long life.
Off-grid system pricing starts at around $15,000 (which would energy a small summer season batch). Those who are currently not linked with electricity network would benefit from an off-grid electricity system, as connecting to the grid would cost over $15,000. The reason why off-grid systems are more costly is that of it that controls the batteries, along with the batteries themselves. Although battery electricity technology is constantly improving and getting a lot cheaper.
