    Default solar power - reviews

    It would be interesting if people that have solar systems could post their findings on the types of systems they are using - there doesnt seem to be a thorough examination of them here - most people I speak to tell me its too expensive to install and will take about 20 years to see any benefit .

    who is happy with their system ,what make is it,what are you running off it and a rough cost.....I dont ask much lol

    Which is why solar is not a viable option for the world, at least not until the cost per kw drops about 75%.

    $50,000 will buy me power from edenorte for over 33 years.

    I assume we are talking about photovoltaics. While I lived and worked in the DR in the late 90's, I lived 100% with solar. Lights, fan, washing machine, blender, radio can be done with a 200-300 watt system (almost a KW/hr to a little more a day) depending on the number of people in the house. US$2000-$3000 depending on design. A DC refrigerator with separate panels and batteries US$3000+. Solar DC water pump with panels - depends but probably starts at US$1000.

    When you install a pv system 1) you are purchasing 20 years of electricity with the panels (batteries are expensive to maintain), and 2) families who use PV must use energy efficient devices and be concerned with conserving the energy they produce. IF you are will to spend a little more money, you can over design the system for basic daily use.

    With the electrical situation the way it is in the DR, having reliable energy has it's own value. For certain uses and applications, it makes perfect sense.

    Thanks, Tom.

    FTR: Tom F knows what he is talking about. And if you're in an area largely off the grid or with truly abysmal service solar makes sense.

    From the Dominican perspective, probably 10,000 rural stand-alone systems have been installed in the country since the mid 80's. They are normally 50-75 watt systems which charge a car battery to provide basic lighting, radio and a b/w tv. I can't say how many of these systems are still working today, but photovoltaics has been an energy source used for some time now.

    If you look, you will find systems on schools, community centers, and clinics in various parts of the country. Community water pumping systems have been built in various areas. Phone companies have used solar panels and are used for their relay stations and then there were these rural phones installed first by a Japanese group in the 80's and others later by other groups.

    I should do a solar energy tour of the Dominican Republic and show people what has been done.

    The difference is the size of the ststem. One can live very modestly with a smaller system and colse monioring of use. One can use solar as a total substitution vs. the power grid.

    A substantial difference.

    i had never heard of photovoltaics..... so anything is an education to me , I will do more research into it

    I was thinking of a bit of lighting and hot water or maybe a pool pump , not a whole house system
