Photovoltaic solar modules convert the sun’s energy into electricity. Homeowners using these systems enjoy the financial freedom from rising electricity bills, and they experience the comfort and pride of bettering the planet. With numerous environmental and economic benefits, there is just no other electricity production system comparable to photovoltaic solar electricity
Stand-alone PV systems are designed to operate independent of the electric utility grid, and are generally designed and sized to supply certain DC and/or AC electrical loads.
• Common applications are direct power to DC loads, water pumping and telecommunications.
• With an inverter it converts DC to AC & then also power to AC loads
• For systems with no battery the energy is used immediately; only works when it's sunny.
• Systems with Battery Backup can supply power 100% of the time: At night, on cloudy days and when the utility power is down.
Grid Tie System is the simplest and most cost effective way to connect PV modules to regular utility power.
Grid-Connected systems can supply solar power to your home and use utility power as a backup.
As long as there is enough electricity flowing in from your PV system, no electricity will flow in from the utility company.
If your system is generating more power than you are using, the excess will flow back into the grid, turning your meter backwards.
If utility power is reliable and well maintained in your area, and energy storage is not a priority, you don't necessarily need a battery. But if the utility power goes down, even if there is solar, the PV system will be off for the safety of the utility workers.
Systems with Battery can supply power 100% of the time.
