MPPT without a battery
I found a mppt solar charger ... but again I don't want the bulky battery.


If you don't want a battery, why did you look for a charger?!


  Can you suggest a way to power a solar charger with a very small battery and not have it discharge when clouds block the sun?


First, when a battery powers something it discharges. That's how it works. Second, most likely there is a way to hack charger schematics to keep it "operational", i.e. powered up without the sun. But what would be the point of that if there is no sun to get power from and no battery to charge?


  Is there a mppt out there that doesn't require a battery?


I believe they called "Direct-coupling photovoltaic systems". You have to research those yourself. The MPPT controllers (not MPPT chargers!) are commonly used for loads that do not have strict power requirements, for example water pumps, water heaters etc.

However the fact is, most loads cannot operate in the wild output power range of the solar panels. Using them without battery basically negates the efficiency gains of the MPPT, because they will shut down in low light when just a little extra juice from the battery could have kept them working. At the same time in very bright light the extra available power is wasted when it could have been used to top up the battery.

So if your device (you haven't given us enough details) is the kind that can operate intermittently and you want it to draw as much power as available but don't mind shutting down in low light, then MPPT controller is what you need. 

If you want your device to have stable operation in variable light conditions then what you really need is a bigger battery and MPPT charger. Then you can limit power available to your device at say, stable 100W 10V and use the remaining 20W (when they available) to charge the battery.
