If you’re considering installing a solar power system in Frederick you will find there are basically three options. For households, these are grid-tied systems, off-grid systems and hybrid systems (a combination of both). If you are requiring a commercial installation, your options are much the same, with the addition of a concentrating solar power system. This is constructed on a much larger scale and makes use of reflective surfaces to concentrate sunlight. The thermal energy produced is then harnessed to create electricity.

A Grid-Tied Solar System

The benefit of using these types of systems is that any unused energy can be directly fed to the power grid. For this, it is possible to get a feed in tariff from the energy supplier. It is possible to run these systems independently of a grid connection, but this will involve extra costs in storing the energy. These systems use natural resources when and if they are available. When they are not, then energy is taken from the grid.

Off-Grid Systems

This systems stand alone and works independently of the power grid. It is a great option in areas where utilities are limited, as well as for those who are looking to live more off the grid. Extra equipment is required, as there needs to be a way to store the excess energy. This can be done using batteries or other energy storage devices. The attraction of living completely independent of any outside energy provider is a very attractive option for many people. There is a downside to these types of systems. Unused energy is often wasted, as storage will be limited. In certain locations, there are also regulations that stipulate that businesses and homes must be tied into the local grid, so check local laws and regulations before installing an off-grid system in Frederick.

Hybrid Systems

The best of both systems is also an option with hybrid systems. Investment in a battery storage system is still required, with the traditional utility system acting as a back-up. A certain amount of planning is necessary in order to make the best use of these systems. Get it right, however, and using the power grid will only be necessary when there is limited sunlight or high levels of energy are required

Off-Grid Versus Grid-Tied

Both types have their advantages and disadvantages. Grid-tied systems can be installed by an expert DIYer, or with the help of a qualified electrician. It is also a little less expensive, as there are fewer requirements when it comes to equipment. The cost of grid-tied systems can also be offset because there are rebates and tax credits available.
