130kW is a lot of power. The average 5 person home will only use a maximum of up to 20kW (if that).
Solar panels, the type that produce electricity, come in 2 types - cheap & expensive. If you are foolish enough to buy the cheap panels (less than 10 years guarantee), you have more money than sense. Good quality solar panels are guaranteed for a minimum of 15 years (subject to installation procedure & method).
If you are serious about saving money with electrical energy, you may invest in both wind & solar technology, as one will support the other. Wind power is cheaper & providing you have the facilities, you can easily build a wind powered electricity generator yourself.
Of course, using either of both technologies requires the use of batteries, something which is expensive & complicated.
About the cost of supplying domestic power:
In Thailand many foreigners have been led to believe that they needed to pay for the installation of transformers etc. This has been proven to be wrong. The foreigners who "put their foot down" ended up not paying anything.
Like most other energy suppliers in the world, an energy supplier will "promise" by government legislation, to supply power in the areas where they must. Consequently, if an energy supplier is charged with supplying customers with power, they must do so at their (the energy suppliers) cost.
Usually, this only involves supplying power up to the property boundary line. After this point, you must pay.
For example, my parents live on a small property outside of town. The power runs past the property but the house is 2km away from the property boundary. The only cost they had to pay was the connection from the property boundary to the house. They were very lucky as their installation is not within a residential area & as such, they may have been required to pay for a transformer.
Here in Thailand, many foreigners stupidly pay the cost of installing a new transformer in residential areas when the power runs past their door. This is not legal by Thai standards & they are being ripped of by corruption. The energy supplier in Thailand MUST supply power to them as promised.
In other words, the only thing you should have to pay for is the connection from the street pole to your house...unless you live in a non-residential area.
