How does an Off-Grid Solar Electric System Work?
There are three types of solar electric systems: grid-direct, off-grid, and hybrid. Each system has its own distinct features that
set it apart from the others, and each has its pros and cons. The most common installation of new solar electric systems belongs to the grid-direct category.
Solar Power Return on Investment
For all of the investments we make in life, there is always an ROI, or return on investment. This is also true of solar electricity, which uses solar technology. The ROI in solar electricity stems from energy conservation and the level of the system’s efficiency. For example, a small PV (photovoltaic) system can handle all of your electricity requirements as long as energy is conserved or used in the most efficient way, such as by switching off power when light is not required or when an appliance is not in use.
While you must first decide between solar thermal and PV installations, you might want to consider utilizing both options when installing your solar energy devices. But to begin, there are several steps an installation of solar energy requires.
REC, or Renewable Energy Credit, goes by many names: Alternative Energy Credit (AEC), Solar Renewal Energy Credit (SREC), and Green Tag. These credits are ways of encouraging “green” energy purchases by making renewable clean energy resources more profitable and more attractive than continued dependence on fossil fuel energy.
There are a lot of factors that can affect the cost of a solar heating system. Besides the variety of sizes, there is a wide range of systems to choose from, depending on the needs of the building owners and the climate of the given location. Moreover, if there is a lack of clarity regarding federal tax laws, price variations for solar heating systems can vary considerably.
