You don't need LOFAR scale aperture to receive solar radio bursts. I literally do it with a ~meter size antenna sitting outside on my porch. Seeing the frequency drift in solar radio bursts is quite easy all things considered. The lowest hanging fruit there is. As for the fine timescale structure of solar radio bursts, depending on frquency, and for this you're probably wanting to cover all of l-band and up, you only need about a meter^2 of aperture. And to see the fine-structure you only need a fast enough receiver with wide bandwidth. That's a few hundred to a thousand bucks. And you definitely don't need to do any sort of imaging or array stuff. All you need is a single receiver and to look at the spectrogram with a time precision of milliseconds. It is very amateur accessible despite the fact that even the largest, most complex, radio telescopes are looking at it too.
