Mono vs Polycrystalline Solar Panels

Both Monocrystalline and Polycrystalline Solar PV Panels are made from Silicon

The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from silicon fragments melted together.

Monocrystalline solar panels

The main advantages of monocrystalline solar panels are higher efficiencies.

Silicon is formed into bars and cut into wafers to manufacture the cells for monocrystalline solar panels. These panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. Because cells are made of a single crystal, the electrons have more room to move to generate a flow of electricity. Therefore, monocrystalline PV panels are more efficient than polycrystalline PV panels. Read More

Solar PV System Finance

Do you need finance for your Solar PV system?

The decrease in Solar Photovoltaic (PV) systems costs over the years can be attributed to the increase in demand and major technological advances. Other factors such as increased property value, municipal incentives, tax benefits and electricity price hikes have boosted demand for PV systems.

One of the major issues homeowners and businesses still encounter in installing a PV system is the high up-front cost. However, these upfront costs are no longer a barrier in the South African decentralised energy market. Innovative financial mechanisms exist that require no upfront capital from the customer.

Off-Grid, Grid-Tied or Hybrid Solar Systems

What are the Benefits of Grid-Connected Solar Systems vs. Living Off the Grid?

Deciding whether to go grid-tied or not is usually pretty straightforward – the clear-cut benefits of being grid-tied appeals to the majority of homeowners. There are, however, some people that choose to live off the grid. What would be the best in your situation? Let’s look closer at the benefits and downsides of grid-tied, Off-Grid and hybrid solar systems.

Grid-Tied Solar Systems

Grid-tied is a term used to describe a solar system that is connected to the utility power grid.

Advantages of Grid-Tied Systems

1. Cost Less

Batteries and other equipment are required for a fully functional Off-Grid solar system and add to costs as well as maintenance. Grid-Tied solar systems are therefore generally cheaper and simpler to install.

Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries. Read More
