4 Factors that Affect Your Solar Inverter Prices

4 Factors that Affect Your Solar Inverter Prices

One of the first things that comes to people’s mind when they decide to go solar is the cost of installing a home solar system. And that makes sense because one of the reasons people switch to home solar power systems is to save money. If you, too, are planning to go solar and are not sure how much a home solar power system is going to cost you, we are here to help. In this post, we discuss some of the factors that will affect your solar inverter prices.

Let’s find out what those factors are.

Your Load Requirement

It is one of the most important factors that affects the pricing of your solar inverter. So let’s say if you need to  run appliances like a washing machine, air conditioner, microwave using your solar inverter then you would have to spend much more than you would be spending on a basic inverter that is simply used to run appliances that consume very less power like tube lights, fans, LED TV and others.

Inverter Type (On-Grid or Off-Grid)

There are two types of inverters – off-grid and on-grid (also known as grid tied). An off grid inverter would require you to invest heavily in batteries. You may even have to purchase multiple batteries. An on grid solar power system on the other hand is connected to the grid, and therefore doesn’t require any battery. It draws power from the solar power system. In case there’s a deficiency it draws power from the grid. Similarly, if there’s surplus power, it transfers that power to the local grid which gets adjusted in the monthly electricity bill.

Inverter Technology (PWM or MPPT)

Based on technology, solar inverters can be categorized into two types – PWM and MPPT.

PWM – Pulse Width Modulation

MPPT – Maximum Power Point Tracking

The PWM solar charge controller is like an electric switch between the solar array and the battery. It is cheaper as compared to an MPPT charge controller but it is less efficient. That’s because a PWM charge controller requires the voltage of the solar array to be equal to the battery’s voltage. And therefore, when the battery’s voltage is low the solar panel’s voltage is also brought down thereby reducing the power inflow.

The MPPT, on the other hand, is more efficient. It tracks the solar panel voltage and current in real time and alters the output voltage accordingly to ensure maximum power output. But as mentioned earlier, solar inverters with MPPT technology are more expensive.

Solar Panel Type You Choose to Install

Solar panels are available in two types – monocrystalline PERC and polycrystalline. Whether you should buy a monocrystalline PERC panel or a polycrystalline panel would depend upon factors such as roof space, performance in lowlight conditions, budget and more. Let us try and understand this with a few examples.

The monocrystalline PERC panels take up less space as compared to polycrystalline panels. So let’s say if you don’t have enough roof space to accommodate the number of polycrystalline panels required to fulfill your home’s power requirement, you can go for monocrystalline PERC panels as they would require less roof space. Similarly, if you are faced with low light issues in your area then you should opt for a monocrystalline PERC panel that’s more efficient as compared to a polycrystalline panel. However, if you don’t have any space constraints or low light issues then you can choose to install a polycrystalline panel that’s much cheaper and can therefore save you a lot of money.
