Batteries allow households to maximize self-consumption of their solar energy and reduce feed-in tariffs from utilities.

Net metering is a billing system used by utility companies to allow customers with solar photovoltaic (PV) systems to receive credit for the electricity they generate. Under net metering, when a residential house generates more energy than it consumes, the excess power is sent back into the grid and credited against future bills.

Utility companies typically have policies in place that establish the amount of credit customers can receive for this excess power. In many cases, credits are applied at retail rates–the same rate that customers pay for purchased electricity from their utility provider–and may be applied toward future electric bills until consumed or rolled over month-to-month up to 12 months depending on state regulations. If a customer has an annual surplus of credits, some states require utilities to pay customers cash compensation for any unused kilowatt hours (kWh).

Utility companies must also provide all necessary equipment and services needed to measure net metering output and process payments appropriately. This includes installing two meters: one to measure total energy generated and one that measures how much energy flows in either direction between a customer’s home and the grid.

When installing solar PV on a flat roof, there are several considerations that should be taken into account.

Roof Orientation and Shading: A south-facing roof will capture more sunlight than any other direction, while west-facing roofs are also well suited for PV systems. Roofs that face east may still be good candidates depending on other factors such as nearby trees or buildings that could cause shading issues during certain times of day. It’s important to consider any nearby objects that could cast shadows on the rooftop array over time such as nearby trees or tall structures like chimneys.

Electrical System: In order for a PV system to generate electricity it must be connected to an existing electrical panel in your home; this connection is necessary in order for power produced by your panels to feed into your home’s grid-connected electrical system. The size of your current electrical panel should also be considered since it may need upgrading in order to accommodate larger loads resulting from adding additional components such as batteries and/or electric vehicles chargers in addition to your PV system.

Monocrystalline solar panels are made of single-crystal silicon wafers and are typically the most efficient type of solar panel, providing higher efficiency rates than other technologies. These cells also have a sleek, all-black look that makes them aesthetically pleasing to many homeowners. Polycrystalline solar panels use multiple smaller crystals within their cells, making them less efficient than monocrystalline but still relatively effective when it comes to energy production. Thin film solar PV panels are comprised of layers of photovoltaic material deposited onto a substrate. They tend to be less expensive and more flexible than traditional crystalline silicon modules, but they also offer lower efficiency levels and shorter lifespans due to their thin construction.
