Solar Power Products

Solar Power Products covers photovoltaic generation and the equipment built around it: monocrystalline and polycrystalline modules, batteries and storage banks, charge controllers and inverters, solar LED street lighting, solar water pumping sets, and complete off-grid and hybrid power plants. EMC Machines Manufactures sizes these from a load profile rather than from a monthly electricity bill, because what a solar installation has to meet is demand hour by hour.

The two errors that spoil most solar installations are sizing from an annual average and treating the battery as an afterthought. A system sized for average sunshine goes dark through the rainy season, and a battery bank sized without regard to depth of discharge fails in a fraction of its expected life. Chemistry matters here: lead acid is cheaper to buy and should not be deeply discharged, while lithium costs more initially, tolerates deeper cycling and usually works out cheaper over the installation's life.

Solar is one of the most heavily tendered and donor-funded categories anywhere. Rural electrification agencies, energy ministries, water and rural supply departments, education and health ministries electrifying schools and clinics, municipal corporations for street lighting, agriculture departments for solar pumping, and renewable energy and rural access projects financed by development banks and climate funds all procure through formal bidding. Our offers are prepared line by line against the specification and carry module and battery datasheets, system sizing calculations against local irradiation, make and origin declarations, warranty terms including module and battery warranties, installation and commissioning scope, operator training and third-party pre-shipment inspection.

Send us your load profile through the day, your location and your required days of autonomy, and we will size the system and quote it.
