What Affects the Cost of a Solar System? Key Factors


As a Photovoltaic Solar installer, this is one of the most frequently requested questions. And it’s understandable.

The solution, on the other hand, can be a little trickier. Although we’d love to be able to provide each customer an exact monetary amount right away, solar energy is not really a one-size-fits-all answer.

Every solar system is individually tailored to match the demands of each property, as well as the tax and incentive benefits.

As a result, a number of factors will influence the final cost.

A solar panel system is intended to cover as much out of your energy use as is cost-effective. Our goal is to supply you with a solution that meets your requirements while also providing the quickest payback period and highest return on investment.

Solar Panel System Pricing Factors

Installation Types

Solar panel systems come in a variety of shapes and sizes. The most prevalent are roof mounts. Grounded mounting and carports, on the other hand, may need the use of additional supports that must be fixed into the ground. Increased labour and component expenses may result as a result of this.

Equipment Types

Solar panels have two primary variables: Colour and density of power.

The amount of electricity a solar cell generates per unit of size is referred to as power density. The greater the cost per watt, the more ‘power dense’ the screen is and the 10kw solar system price will increase. Solar panels also come in a variety of colours.

A basic panel has a silvery frame, a blue cell, and a white backing sheet. Module with a black frame will also have a black backing sheet or black cell, and will cost extra.

String Inverters

solar pv panel in one or more groupings, are joined together. Each cluster feeds into a ‘string inverter,’ which is a single inverter that feeds multiple panels. String inverters are less expensive than some other inverter kinds, making them a popular choice among households.

Micro Inverters

If any or several of your solar cells are shadowed, micro inverters are put next to them to avoid performance concerns. Although this sort of inverter has its own set of advantages, it is also the most expensive.

Power Optimizers

Many of the advantages of micro-inverters are available with power optimizers. They’re costlier than string inverters, but much less costly than micro-inverters.

Type of Roof

On steel, flat roofs, and shingle solar panels can be put. To construct each style of roof, various components are required, as well as varied amounts of effort.

To connect the panels racking to the roof on a shingle roof, a special flashing piece is required. Equipment is attached straight to the metal on a corrugated or standing seams metal roof. A grounding mount — a tray kept in place by a concrete block – is used to install panel on a roof deck.

Consumption of energy

The majority of solar panels are built to offset quite so much energy use as possible. The method will, nevertheless, need more equipment and panels as the amount of energy output required increases. Each homeowner should think about finding the ‘sweet spot’ of expense and energy production.

Weather and Shading

It’s crucial to think about the surroundings around your solar panels. The number of panels required and their location will be determined by how much shadow your yard provides. A system in full sun may create more power with less panels, whereas a system in the shade would require more panels to generate the same amount of power.
