One of the first things to consider when choosing a generator for your farm is whether you will require a petrol or diesel generator. Petrol generators have been around for longer than diesel generators but this doesn’t mean that they are always the best choice for your farm. Petrol generators cost less to buy and generally have lower maintenance costs. While diesel generators are generally more fuel efficient especially when compared to petrol generators with high RPMs but the cost evens out with petrol generators with low RPMs. While a diesel generator will cost you more initially and can have higher maintenance costs, it is more likely to have better longevity and should need maintenance less frequently than a petrol generator. You need to consider what the purpose of your generator is going to be. If you’re going to be using it for emergencies, already use petrol for your other machinery and require a generator with low RPMs, you should consider a petrol generator. However, if your generator is going to be a primary source of energy and operate larger systems, it may be wise to invest in a diesel generator. 

A portable generator is a powerful yet economical solution to your small farm electricity needs. These are perfectly suited for emergencies and occasional use but may be sufficient for your small farm needs. They can be moved around easily and cost much less than a permanently fixed generator but need to be well looked after in order to prolong their lifespan. Standby or stationary generators are more expensive but generally last longer than portable generators and need less maintenance. If you’re going to be using your generator often and need a strong, reliable power solution, a larger standby generator might be more suited to your farm.
