Solar panels have an average lifespan all the way to 30 years so let's wait and watch how many generators you need to last you 30 as well as how perhaps you will need to "fill 'er up" to obtain some potency. On this basis alone solar powered energy is more desirable. If it's a question of start up costs it is easy to always just be sure to get it factored with your mortgage consequently it becomes the principle rent payment and not an extra. Store generators from they were intended for and that's for emergency use only limiting their use to a couple of hours at any given time.
In today's market, the generator buyer has many to choose from. My first choice to pull up quickly is a conveyable 300kw diesel Generator generator. Diesel generators normally cost nowadays up front but they'll out last gas generators if maintained properly. When viewing portable diesel generators, and the wonderful you want to think about are ones with engines that turn at 1800 rpm.
