Energy Upgrade California – Model of Efficiency

We work with Energy Upgrade California to do Home Energy Analysis to determine what you can do to reduce your energy usage. We also recommend energy efficient technology that can save you money, such as solar panels and tankless water heaters. Below is a video made by Energy Upgrade California demonstrating some of the energy upgrades some home owners are doing to save on their energy bill, and make their house more comfortable.


Energy Upgrade California was also on KPBS recently talking about how they want to help Californians reduce energy usage by atleast 10%. Watch that video below.



Water usage contributes to 90% of energy usage. That includes heating, transporting, and landscaping. Solar panels are become a good option to produce your own energy and lower the amount you use from the grid. There is a 16 minute radio piece from “Morning Edition” on the KPBS website that has even more information about energy usage. You can listen to that by visiting the KPBS website:

Solar System Installation Cost Calculator

How much do solar panels cost to install on your home?

It depends on how much electricity you use in your home. The amount of electricity you use will determine how large a solar panel system you get installed. The most cost effective solar panel system installation is when your electric bill is high and you are paying over $100 a month to SDGE. That monthly utility payment can be brought down to zero, and instead that money can be spent on paying off a loan for a solar electric system you own. The larger the system, the more money you save in the long run.

Another aspect to take into account is once the solar panel system is paid off, that when you gain the most benefit. To determine how long it will take to get there, you will need to do some calculations. Below is an estimate on how much you can expect to pay based on how large of a solar panel system you get installed:

Why you should Buy your Solar System with a Loan instead of Lease

Our goal is to get you the best deal on a solar electric system for your home. We work with you to help you make good decisions about how to lower your energy bill and increase the value of your home. We recommend buying your solar system and getting a loan to pay off the purchase over 8 to 20 years. This is a much better decision than signing a lease.

Other solar companies out there may try to get you to sign a lease with them. This means they own the solar electric system, and you rent it from them. The advantage of a lease is if there is an rare chance that the solar panels break, they will repair them for you without any charge. The dis-advantage is it is MUCH more expensive for several reasons. First and most influential is that you don’t get the federal tax rebates, 30% Federal Tax Creditwhich can be around $10,000. Second since leasing cost more, their goal is to match your current monthly electric bill payment. That means you don’t actually save any money. Some leases include payment increases over time which match utility rates increase. Continue reading “Why you should Buy your Solar System with a Loan instead of Lease” »

Financing Available for Energy Efficient Products

We can assist you in getting an Energy Efficiency & Solar Loan through San Diego Metropolitan Credit Union. These loans make purchasing upgrades such as a Solar Photovoltaic System, or replacement windows affordable without needing to pay a large amount up front. Pay off the cost for the energy efficient product over time as you save money on your energy bill.

Program parameters include:

  • Single family residential homes located in San Diego County
  • Below market loan rates
  • Fixed rate loan up to a maximum term of 20 years
  • Loan amounts up to $25,000 – Energy Efficient Home Improvements
  • Loan amounts up to $50,000 – Solar Photovoltaic Systems
  • Establish a loan loss reserve account with Installation Services of San Diego

The American Recovery and Reinvestment Act of 2009 allocated funds to the City of San Diego to support energy efficiency programs that benefit its residents. Working with existing energy efficiency incentive programs offered by Energy Upgrade California (EUC) and CSI– Thermal, the Home Energy Loan Program  makes it more affordable to conserve energy and save money on utility bills. At the same time, upgrades can increase the comfort, health, safety and value of the home.
