Introduction

Congratulations

Welcome to Alternate Energy Inc's. Energy Analysis and Proposal for a grid tied photovoltaic system to be considered for the Proposal's residence of 1234 Test St. The purpose of this document is to illustrate the advantages for you, your household and the environment by installing a gridtied photovoltaic system with Alternate Energy Inc.

Three Generations

Alternate Energy Inc. (AEI) is a familyowned and operated business with a long history of serving kamaaina. More than 30 years ago, Bruce Ekimura, a plumber by trade, realized that harnessing the power of the sun could help Hawaii families combat the rising price of electricity and help our state become less dependent on imported oil. Bruce and his father became early specialists in the installation of solar hot water heaters, and later photovoltaic (PV) systems, and in 1993 Alternate Energy was officially incorporated.

 

Today, as rising oil prices continue to keep electricity rates soaring, Alternate Energy remains committed to helping local families and businesses discover the clean, green, moneysaving power of the sun.

Elite Installer

Alternate Energy Inc. recently achieved the status of Panasonic Solar's first and only recognized Elite Installer in the state of Hawaii. This means that we are Certified and trusted by Panasonic Solar
to sell and install
its premium monocrystalline solar panels in Hawaii.

Elite Training & Certification

All of our highly skilled solar technicians are employees (not subcontractors) annually Trained and Certified by Panasonic Solar to design, install and service all of your PV needs.

 

Elite Products

We understand that photovoltaic systems are a long term investment. That's why we invest in the most reliable companies that have been trusted for years. Panasonic Solar's premium solar panels are among the highest efficiency and highest rated panels in the industry.

The solar panels are also designed and warrantied for installations near salt water for long lasting performance.

Elite Service

Being family-owned and operated, we take pride in every job and make sure each customer is satisfi ed, every time. We are Hawaii's expert solar company since 1993.

This system will prevent 86.65
lbs sulfur dioxide (causes
acid rain) from being released
into Hawaii's rainforests.
