Solar System Calculator (SSC) - free, easy-to-use web tool to size solar panels, batteries and inverters for residential off-grid systems. Calculate load, inverter size, battery capacity and panel wattage in minutes.
For most applications, a good rule of thumb is to aim for a 1:1 ratio of batteries and watts or slightly more if you live in regions with limited sunlight, such as near the poles.
To ascertain the right size of a capacitor, it's essential to consider various factors, including total wattage, voltage ratings, and load demands. A common starting point for calculation is using the formula: Capacitance (F) = Load (W) / Voltage (V)².
In 1954, scientists at Bell Labs created the first practical silicon solar cell, marking a significant step forward. These early panels had very low efficiency - around 6% - but they paved the way for future developments.
This calculator estimates the required wire size for a solar system based on the system voltage, total wattage, distance to the panels, and desired voltage drop.
MC4 is the name of the connection type on all new solar panels, providing an IP67 waterproof and dust proof safe electrical connection. MC4 will not connect with older MC3 type connectors. The MC4 connectors work best with 4mm and 6mm solar cable.
Article 690 of the NEC mandates that #8 AWG or #6 AWG are the smallest wires that can be used with grid tied solar panels and inverter systems, and for solar panel output circuits, #10 or #12 AWG are allowed. A ground rod is also recommended if the installation area is prone to.
A solar battery captures excess electricity from your solar panels and holds it for later use. Instead of sending surplus power back to the grid or losing it entirely, a battery lets you bank that energy and deploy it on your own schedule.
