Solar Nexus International sells systems, not components.
Our systems convert sunlight into electricity for charging batteries and powering homes.
We have tried to simplify the design and installation of off-grid solar PV systems by reducing the number of primary components into four main parts:
1. The load - the lights, appliances, tools you need to power
2. The charging source - photovoltaic (PV) panels, wind generator or microhydro turbine.
3. The battery - sealed or flooded lead acid
4. The NEXUS pre-wired power center
System sizing is broken down into two main load variables, POWER and ENERGY
High power loads include deep well pumps, power tools, some home appliances and air conditioners. Low power loads are things like lights, computers and efficient home entertainment devices. So how much POWER do you need for your application? Many times efficient small homes can be powered with just a few hundred Watts of electricity.
To size a system we select the proper NEXUS to match the need for POWER. Our Nexus products range from 300 Watts to 30 kW.
Next, we ask the question, how much ENERGY do you need? This means for how much TIME are you going to need to be using the solar POWER? Energy is measured in Watt-hours (Wh) or kiloWatt-hours (kWh) and we use that number, along with geographic and other information to determine the size of the PV array, battery bank and back-up generator required.
