Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight into electricity. The cost per watt is a key metric used to compare different solar panels and determine the return on investment from a solar energy system. According to Solar Exporters, a leading solar panel manufacturer and supplier based in China, the cost per watt depends on various factors such as panel efficiency, size, warranty period, and more.

Overview of Solar Exporters

Solar Exporters is a professional solar module manufacturer with over 12 years of experience in production and quality control since 2010. They guarantee energy independence through their high-quality solar panels and positioning themselves as solar service professionals. Some of their offerings include:

They provide customized solar solutions for homes, businesses, and large-scale projects. Their team can help determine the right system size, components, and installation based on energy needs and budget.

What is Cost Per Watt?

The cost per watt ($/W) refers to how much a solar panel costs for each watt of energy it can produce under ideal conditions. For example, a 300W solar panel that costs $300 would have a cost per watt of $1 ($300 ÷ 300W = $1/W).

The cost per watt metric allows easy comparison between different solar panels. It also helps calculate the payback period and return on investment from a solar energy system. A lower $/W means lower overall system cost for the same energy output.

Typical cost per watt range:

  • Residential solar panels: $2.50 – $3.50/W
  • Commercial solar panels: $1.50 – $2.50/W

Cost per watt has decreased over 85% over the last decade, making solar energy more affordable and accessible.

Key Factors Affecting Solar Panel Cost Per Watt

There are several key factors that impact the cost per watt of solar panels:

1. Efficiency

Higher efficiency solar panels can produce more electricity from the same surface area. For example, a 300W, 20% efficient panel will take up less roof space than a 300W, 15% efficient one. More efficient panels have a lower $/W since the power output is higher for the same cost.

Typical residential solar panel efficiency ranges from 15% to 22%. More expensive monocrystalline and SunPower panels reach above 20% efficiency.

2. Size and Power Output

Larger and higher wattage solar panels have a lower $/W, but might cost more upfront. Optimal solar panel size depends on available installation area and energy usage of the home/business.

Typical residential solar panel size:

  • 60-cell: around 300W
  • 72-cell: 360-400W

3. Warranties

Reputable manufacturers like Solar Exporters provide long warranties of 25-30 years to back the reliability of their solar panels. Such warranties add slightly to the $/W but give financial protection.

4. Quality and Brand

Premium solar panels made with higher grade materials and advanced technology have higher $/W but also higher energy yield over their lifetime. Top brands like LG, Panasonic and SunPower are on the pricier end.

5. Pricing Factors

The $/W rate also depends on:

  • Bulk ordering: Bulk purchases decrease cost through discounts
  • Import duties/taxes: Varies by country and import regulations
  • Exchange rates: Currency fluctuations impact international pricing
  • Installation costs: Not included in panel $/W but affects overall price

Cost Per Watt of Solar Exporters’ Panels

As a China-based solar panel manufacturer, Solar Exporters provides very competitive pricing while maintaining quality standards through their years of R&D and expertise.

Some example cost per watt rates for their panels based on the power output:
