If you’re looking for a solar company in Erie, CO, you won’t have a problem, because there are a number to choose from. Do the right kind of homework and picking the best one will not be a problem. Part of the homework will involve finding out about the different types of systems and whether off-grid or grid-tied is the best.
Grid-Tied Systems Are Very Popular
Choosing a grid-tied system is a popular choice. It is one that is interconnected with the local power grid. Why is it such a popular choice? Because there is a 30% federal tax available. This, of course, will soften the blow when it comes to cost. Many of the utility companies also offer a variety of rebates. Other valid reasons include the lack of maintenance required and the fact that it is an automatic system.
The downside of this type of system is worth mentioning, because it can make a significant difference. There are very few utility companies that promise no blackouts. They happen from time to time and can be very inconvenient. If you choose to use a grid-tied system you don’t get to miss out on these blackouts. Even if the sun is shining, you will experience the same as everyone else using the grid. It is possible to make use of batteries to overcome the problem. But this will inevitably add to the cost of any system used.
A System to Meet Your Needs
A system such as this will be more than adequate for producing all the energy most domestic customers would need. If you’re not sure how much you use it is possible to get this information from your utility company. Ask about the average kWh (kilo-watt hour) used over the last twelve months. This will indicate how much you need to be able to generate with your renewable energy system.
How a Grid-Tied System Powers a House without Batteries
A grid-tied system only produces energy during the day, but it is able to help provide power for a home twenty-four hours a day. It uses something called net metering which means the electrical grid becomes the storage for any excess energy. The energy is back-fed through a circuit breaker into a homel. Any energy needed to power loads in the house is provided, and the extra is fed back into the grid. Think of it as the meter spinning backwards when the excess energy is fed back into the grid. Customers are able to offset the energy used, regardless of the time of day and no battery storage is required.
Panels for this type of system are usually installed onto a rood. However, they can also be installed on the ground. A professional solar company in Erie, CO will be able to advise on the best type of installation. It will also be able to suggest the optimum location for any solar panels. South facing is the ideal direction for all types of collectors, because the sun rises in the East and sets in the West.
