Residential Solar Power System
Solar energy is the cleanest, most abundant, renewable energy source available to offset residential power consumption. For a homeowner, it provides an effective option to decrease the monthly cost of your electrical bill, including protection against rising rates in the future, and can ultimately reduce your carbon footprint.
Photovoltaic (PV) systems are used to convert sunlight into electricity. Solar panels, inverters, breakers, and mounting equipment make up a PV system’s main components. Solar panels (modules), the system’s main component, generate power by converting sunlight to direct current electricity. Inverters convert the direct current electricity to alternating current electricity to be used in your home.
Two Main Types of Solar PV Systems
- Grid inter-tied systems: Feeds alternating current electricity directly to the local grid and residential property. (This system allows the house to draw on the solar cells as well as the traditional power grid for electricity, seamlessly switching between the two as necessary).
- Off-grid systems: Stores direct current electricity in batteries for later use. (This system operates independently from the grid and provides a household’s entire electricity, eliminating your electric bill altogether).
Residential Grid-Tied Solar Electric Systems
- Rooftop solar panels are the most common and are mounted on your home and/or garage.
- Solar panels on your home also provide energy independence for your electric cars; electric vehicle charging can be done from your home’s solar power.
- When your PV system production exceeds your demand, for instance at night or rainy days, the extra electricity is fed immediately to the grid; the bidirectional meter, provided free by the utility, tracks the exported energy and the utility reconciles credits for usage (net metering), which is reflected on your electric bill.
Solar Site Residential Assessment
Prior to any solar electric installation, Rikur Energy provides a detailed and comprehensive solar site assessment, which includes:
- Accurate measurements of your roof or ground space including locations of plumbing stacks, chimneys, skylights, attic vents, etc.
- Shading analysis from proposed location for solar (sometimes several points need to be analyzed to determine the best location); this data is used to provide accurate energy production estimates.
- Discussion with homeowner to determine route of cable from site of solar electric array to location of inverter/mains panel.
Residential Solar Power Installation
- Initial estimate: If high quality satellite images are available, we can provide accurate estimates for system size and energy production for your specific house.
- Site assessment: We execute a site visit to obtain detailed site-specific information required for a solar installation including, detailed roof measurements, electrical capacity of your electrical system, and a shading analysis (if required). For new residential construction, we can design a system from the architectural drawings.
- System design & quote: We will design a system specific to your roof space, budget, and electricity needs. Rikur Energy provides a design to show your roof’s appearance with solar panels as well as an economic analysis.
- Permitting and grid connection application: Rikur Energy takes care of all the permitting required (electrical, building and/or development permits) and the application to inter-connect the system to the grid.
- Installation and commissioning: The Flush Mount system and flat roof Ballast system is installed by our highly trained and experienced installation crews.
- A typical solar installation on a residential roof is 24-32 PV panels.
- This number of panels typically generates 7,560 – 10,200 kilowatt hours of electricity over a year.
Rikur Energy offers complete turnkey solutions for your renewable energy installations on your home, which includes permits and grid connection applications. We will provide preliminary cost estimates, energy production, and an economic analysis specific to your home. Unfortunately, there are no government incentives for residential solar systems in British Columbia at this time.
