How Much Does Solar Power Cost

What Does Solar Electricity Cost

How much do solar panels cost?

As shown in the chart at the left, photovoltaic solar cell prices have come down by a factor of 100 over the last 38 years and down by a factor of 25 over the last 15 years. The sharp drop in 2009 and 2010 was because of too much capacity, especially in China, which has caused prices to collapse. The 2015 average solar “cell” price was $0.30 per watt and the average solar “module” price was $0.72 per watt.

Since costs after installation are minimal for solar electricity, the relevant costs are the purchase price, installation costs, and the cost of land . Cost components that make up a residential solar system are: system design, solar modules, and the balance of system which consists of an inverter, bi-directional billing meter, connection devices, and installation labor.

In the southwest, installed residential solar prices are competitive with residential electricity prices after incentives.

Cost Per Watt
Utility Scale – Tracker $1.13

According to the National Renewable Energy Laboratory , located in Golden Colorado and Washington DC, the average residential household in the U.S. installs a 5 kWh system and it cost on average $2.70 per DC watt or $13,500 before incentives. Utilities on the other hand typically install systems in the 100 mega-watt or greater range. The average installed “fixed” utility system cost was $1.06 per watt and $1.13 per “tracker” watt. Top

Federal Solar Tax Credits And State Solar Incentives

When you own the home solar system, you are eligible to apply for up to 100% of the available federal and state incentives and rebates.

As this recent article in Forbes magazine explains, the federal solar Investment Tax Credit , which was scheduled to drop from 26% to 22% in 2021, will stay at 26% for two more years and not drop to 22% until 2023. For a $20,000 system, the 26% federal credit would be $5,200, compared to $4,400 under the 22% credit.

Several states also offer solar tax credits and solar tax rebates. People who own their solar system and/or battery in participating states may be able to claim these expenses on their local taxes or receive cashback on their installation. While you may be eligible for a solar tax credit or a solar tax rebate with the purchase of a home solar system, please remember that tax incentives are subject to change.

Different Solar Panel Cost For A 1500 Square Foot House

There are three major types of solar panels based on manufacturing technology:

  • Monocrystalline Solar panel
  • Thin-film Solar Panels

Cost With Monocrystalline Solar panels For 1500 Square Foot House

Monocrystalline solar panel are widely known as single-crystal panels. Because these are made from a single pure silicon crystal. The use of pure silicon also makes monocrystalline panels the most space-efficient and longest-lasting among all types.

However, this benefit doesnt come without additional cost. Lot of silicon is wasted while producing one monocrystalline cell, usually reaching above 50%. This results in a hefty price tag of these solar panels.

Cost With Polycrystalline solar panels For 1500 Square Foot House

Polycrystalline solar panels come from different silicon crystals instead of one. Polycrystalline cells are much more cost effective because there is hardly any wastage. However, these panels are less efficient in terms of energy conversion and occupy more space. These panels are less efficient in high-temperature environments because they have lower heat tolerance than monocrystalline panels.

Above price calculations are made for monocrystalline panels. Exact difference between the prices of different types of panels will vary depending on solar installation company and model. As a rough idea, polycrystalline panels are 20% cheaper than monocrystalline panels but also 20% less efficient .

What Is The Roi On Solar Panels

Solar Panel Costs

You can calculate the return on investment for installing solar panels by calculating your total payback. Calculate the amount you spent to install a solar panel system and then figure out the amount you will save on energy bills monthly. These two numbers show how quickly your savings will cover your initial costs. Electricity rates will vary by region, being higher in the Northeast than in the Northwest. Solar tends to be more cost effective where electricity prices are high and sunshine is abundant.

Solar Thermal Panels Vs Photovoltaic Panels

You may find that in addition to the many other choices you have when it comes to solar, you also have two panel types to choose from. Solar thermal and photovoltaic are the two main types of solar energy. For most homes, photovoltaic is the most common type, while solar thermal is typically used for larger commercial settings.

Solar thermal panels use heat, which it then converts to energy. This means it could store the heat from the day and then produce energy at night. Photovoltaic cells produce electricity from light. This is the most common cell because they can be installed with or without batteries, and they do not overheat. Some thermal panels lose efficiency as they heat up, making them not as good a choice for mounting on top of a home or in very sunny climates. Both have a similar cost per watt, depending on the manufacturer.

How Much Does It Cost To Install Solar Panels

The average cost to install solar panels in the United States is about $12,000 after federal tax incentives. On the low end, you can install a smaller system for around $5,000, while a high-priced Tier 1 solar panel system can cost $40,000 or more.

There are additional costs that go into an installation project beyond the price of panels. In fact, only about a quarter of the installation costs are actually for the panels. Labor costs, operational costs and additional equipment, such as inverters and control circuitry, make up the rest of the price.

Solar energy companies install the solar panels, provide maintenance and offer warranties on both the panels and the work. These additional services arent free, but they are often worth it. A few additional factors affect the price of solar panel installation.

How Efficiency Is Determined In Solar Panels

The efficiency of solar panels is determined by the amount of sunlight that is reflected on the panels surface, which is then transformed into electrical or thermal energy. Previously, the average efficiency of solar panels was around 15%, but thanks to advancements made in the field of photovoltaic technology, efficiency is now over 20%. As a result, 370W is the typical power rating of a panel, an improvement from 250W.

There are two factors that go into determining solar panel efficiency: photovoltaic cell efficiency and total panel efficiency. PV cell efficiency comes as the result of the cell design and silicon type, while cell layout and configuration along with the panel size are the basis for total panel efficiency. Total panel efficiency is determined by the maximum power rating under standard test conditions divided by the total area of the panels .

There are a number of things that can affect efficiency, such as temperature, cell type and irradiance level, which is the rate at which sunlight hits the panels. The color of the backsheet that protects the panels can also affect efficiency. For example, while black might look more attractive for a protective blacksheet, the color absorbs more heat. This results in higher temperatures and therefore a reduction in the total conversion efficiency, so other colors like dark blue, green or even patterns might be a better option for your solar panels.

Standard Solar System Components

As we mentioned earlier, equipment is another factor to consider when calculating how much it costs to install solar panels. Each standard residential solar array uses four components:

Solar panels captures the suns energy and converts it to electricityController protects batteries by regulating the flow of electricityBatteries store electricity for later useInverter converts energy stored in a battery to voltage needed to run standard electrical equipment

The entire system, plus installation, is what drives solar panel costs. Plus, equipment like batteries sometimes need to be replaced over time.

The good news is that the costs for solar panels are expected to continue to drop as thin film panels from companies like First Solar, Nanosolar, and AVA Solar become available to the residential market, which could drop prices to $1-2 per watt and at volumes that are several times todays total output.

Assuming that installation and auxiliary equipment costs can be reduced to around $1 per watt, then a 5 kW system in upcoming years may cost as little as $10,000, with a payback period of about 10 years. This makes the future of PV solar installations much more attractive.
