introduction to solar

The kWh Analytics team is mission-driven, and every member of our team is passionate about advancing the solar industry as part of a larger movement to fight climate change. The solar industry is experiencing very healthy expansion, and we're excited to facilitate the continued growth of solar.

With the help of the Solar Investment Tax Credit (ITC), solar energy is growing quickly both domestically and internationally. Although the ITC kickstarted solar development, solar is now economically viable, thanks in part to lower production costs.

As solar grows, so does the demand for and profitability of new, more efficient solar technology. New research and higher demand have driven down the price of going solar, which has further expedited adoption of solar power.

Solar is widely accepted, and not just in the sunniest states. As prices fall, legislators are warming up to policies that let in solar developers. Solar is worldwide: Japan, Europe, and China are all leaders in solar energy and show no signs of slowing down.

Photovoltaic Basics

Sunlight is the most abundant energy source on earth and solar panels convert it directly into electricity with no moving parts.

• All solar panels use semiconductors to collect the energy from individual photons hitting them.

• If you’ve seen a solar panel, that solar panel was made of photovoltaic (PV) cells which convert light into energy.

• The most common semiconductor material used is silicon, but there are various technologies and other material types all with their own unique strengths and weaknesses.

Types of solar projects:

one (3).png


Capacity: >5-10 MW

A large solar project that feeds energy to the grid, selling it to utility companies.


~65% of the U.S. solar market

Utility-scale solar in the U.S. generates roughly 43.5 GW (43,500 MW), enough electricity to power about 8.3 million homes


The Solar Energy Industries Association (SEIA) reports that there are another 74 GW of large-scale solar developments in progress, enough to power roughly 14 million homes →


Residential Solar

Capacity: 6 KW

The kind you’re probably used to seeing. Homeowners use a number of financing methods to obtain a solar system on their roof that produces enough energy to at least partially offset the energy the home needs to get from the grid.


~18% of the U.S. Solar market

Residential solar in the U.S. generates roughly 12 GW (12,000 MW), enough electricity to power about 2.3 million homes


A household rooftop solar panel system can reduce pollution by 100 tons of carbon dioxide in its lifetime—and this includes the energy it took to manufacture the solar panels. →

Commercial & Industrial Solar

Capacity: 50 kW-1 MW

On-site solar project producing energy for commercial or industrial entities (not electric utilities or residential customers).


~15% of the market

Commercial and Industrial solar in the U.S. generates roughly 10 GW (10,000 MW), enough electricity to power about 2 million homes


As of August 2019, Target owns the largest amount of on-site solar, with 229.7 MW of solar on various Target roofs. Walmart comes in second with 152.1 MW installed. →


Community Solar

capacity: <5-10 MW

Members of a community opt into a program that allows them to buy energy from a larger solar project that isn’t on their roof. Residents pool their resources to own solar instead of buying their own system. Community Solar allows people to participate in solar who could otherwise could not, like those who don’t own the homes they live in.


~2% of the U.S. Solar MArket

Community solar in the U.S. generates roughly 1.4 GW (1,400 MW), enough electricity to power about 254,000 homes


The Coyote Ridge Community Solar Farm in Fort Collins, Colorado will be the largest low-income community solar project in the U.S. at 1.95 MW. →

kWh Analytics has worked with data from and structured our Solar Revenue Put on all these types of solar projects.

What can affect solar production?

Many things can affect solar production, but these are the most well-known:



Factors like sunlight, clouds, snow, and excessive heat can all affect performance. Weather is often inaccurately measured/factored into forecasting.


Solar panels don’t necessarily work best where they catch the most sun! Hot weather can reduce efficiency, and solar panels prove effective even in places like Seattle. →



Inverters turn DC output into AC output that can be fed into the grid. Inverters aren’t 100% efficient, so it’s important to measure how well inverters are converting power.


PV Evolution Labs (PVEL) described solar inverters as the hardest-working component of a solar array. →


Equipment damage

Solar equipment can be damaged before, during, and/or after installation. Proper operations and maintenance management is important.


Solar panels are built to produce energy for 25 years or longer, so companies must account for long-term degradation, component failures, etc. →

Are the solar panels catching as much sunlight as possible? The orientation of a solar panel affects the production, and is defined by both the tilt (horizontal->vertical) and azimuth (N, S, E, W) of the panel.


Some commercial solar projects use tracking systems that change the tilt of the panel as the sun moves across the sky. →



Materials covering panels (like dirt) and growing under and around panels (like vegetation) can affect performance.


Some solar developers are using sheep to control grass around panels. →

kWh Analytics’ industry-leading database gives our experienced data scientists a unique advantage when predicting solar production. Our engineering team is a pioneering force for solar, utilizing all possible data sources to improve solar production forecasting.

Who pays for a solar project?

Investors buy into projects sponsored by different developers, and in return will receive a share of profits when energy produced by those solar projects is sold. Investors receive energy production reports from each developer in their portfolio separately, making it difficult and time-consuming for banks to track and benchmark performance of their entire portfolio.

The Problem

The solar industry is growing fast, but supporting technologies and financial practices for this new asset class aren’t keeping up. Although the costs of solar panels are falling, soft costs, like the cost to secure the capital needed to build a solar project, aren’t doing the same. Investors offer less capital to fund solar because of a high performance risk. Read More ➞
