Why Lithium-iron-phosphate Batteries?
Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of benefits compared to lead-acid batteries and other lithium batteries. Longer life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency, just to name a few. LiFePO4 batteries are not the cheapest in the market, but due to a long life span and zero […]
Standard Test Conditions of PV Module
The three main elements to the STC are cell temperature, irradiance, and air mass – all of which are variable conditions that the PV modules will be exposed to after they’re installed.
Best Batteries for Solar PV System
Today’s solar batteries are better than ever. So are the devices that regulate and protect them. But you still need to do your homework to make sure you get the best solar battery storage solution for your needs. There are two main kinds of deep cycle batteries: lead-acid and lithium. Lead-acid batteries have a lower […]
How to Size the All-in-one Inverters
When specifying an inverter (all-in-one inverter/charger) for any off-grid solar power system, you need to consider the voltage for the loads, the maximum power draw, charging capabilities, and the ability for the inverter to supply power when certain loads surge (draw a large amount of power for a very short duration).
PV Modules in Africa – from Blue Sea to Red Sea
In November 2017, Photovoltaic News told a story of a penniless farmer who went to Africa to sell PV modules and became a legend in billionaire after five years. At that time, the African photovoltaic market was full of gold. But what is the current situation?
Pros and Cons of 60-cell & 72-cell Solar Modules
The summary: 72-cell is about a foot taller, and they cost a bit less to mount in large-scale applications. However, both 60-cell and 72-cell solar modules use the same cell technology, and they work out to the same price from a cost-per-watt perspective. Either option can be used in residential or commercial installs – the […]
