It's a unique tool that provides a depth of analysis simply impossible by any other means at my disposal.

HOMER is powerful and easy to use. I used it in conjunction with ViPOR for simulation of rural electrification systems using hybrid wind-solar in two villages in the state of Bahia in Brazil. This study found such systems to be more profitable than individual photovoltaic systems currently used by local concessionaire. Congratulations to the creators of HOMER!

It allows simple apples to apples comparisons of drastically different system designs. It convinced me of the utility of wind power in my situation. It taught me the importance of a properly sized battery bank. It has provided me with the data to convince most of the stakeholders of the importance of switching from a gasoline generator to a generator/battery/renewable system.

I continue being awed by HOMER. I find it to be a unique and extremely useful resource, often giving insight that had not existed previously. In particular, the inclusion of statistical fluctuations in the simulations and the automatic optimization have saved us enormous amounts of time — if we had actually had the resources to do them by other means.

From our first look at the HOMER software it looks superb, as if written for exactly what we are doing (design, supply and installation of small scale wind power systems for remote and rural applications such as telecoms, cell towers, irrigation water pumping and isolated communities' electrical supply). We thank you for creating this package.

We have been making great use of the HOMER tool. We have been designing solar only [telecom] sites for many years and recently started adding wind to help during winter storms. We didn't have a predictable way to evaluate the contribution from the wind turbine until we started using HOMER last year.

We downloaded HOMER 6 days ago, mainly for optimizing systems in a rural electrification project in Jordan. We find the program easy to use and straightforward and it has been great help in sorting out myriad possibilities. HOMER presents results in a clear and concise manner, making decisions easy.

Northern Power Systems has been using the results of NREL's optimization model, HOMER, for several years now. It is a unique and valuable tool for our core business of designing hybrid power systems for remote applications, such as telecomm, pipelines, village power systems and eco-tourism. HOMER represents the state-of-the-art for analysis of these applications.

Clint (Jito) Coleman
President, Northern Power Systems

I just wanted to express you my satisfaction (I should say my complete satisfaction) with HOMER. I was using it for the last year to simulate RET systems as part of a pre-feasibility investigation regarding the use of renewables as an alternate source of energy for off-grid electrification in Costa Rica. Congratulations for such a useful tool.

Ricardo Jahns
Consultant, UNDP Energy and Climate Change Programme for Latin America and the Caribbean

I recently used HOMER to assess renewables and diesel solutions for an island in Costa Rica, as my project of a renewables course. I find it is very solid and transparent, once you get the hang of it. Keep up the good work.

I'm putting together a comparative database of PV design software in cooperation with Sharp (Japan) Corporation's Ecological Technology Development Center in Nara, Japan. I've found HOMER to be incredibly robust and the best application available for system comparison among the 15 or so programs covered.
